I was wrong about CS:GO's default FOV. I brought out a protractor and measured them manually in this video: https://youtu.be/YJIqFxgaXtY See more stretched FOV footage here: https://youtu.be/FiFdVKRxQYk Want to know what CS:GO is like at different aspect ratios? Want to get more viewing angles AND better FPS? I talk you through a few ways in this video. starting with an easy but offline method and then an online one with pros and cons. 0:22 - FOV with console command. Here's something to get you started on an offline server: sv_cheats 1;fov_cs_debug 120 1:21 - Ultra wide-screen in proper matches. Once again, here's a value to get you started. Use these launch options: -w 1920 -h 540 -windowed OR, (thanks to Pandaclaw), type this in the console in-game: mat_setvideomode 1920 540 1 2:09 - Change your weapon model's FOV using this video: https://youtu.be/qM8EVhPML6w Download CRU here: http://www.monitortests.com/forum/thread-custom-resolution-utility-cru QUESTION: 'You say wider FOV makes FPS lower, but then say it makes it higher!!! How?' Because the amount lost by being wider is outweighed by the smaller resolution. Resolution is the major factor that determines the speed that CS:GO runs at, so having the game run as a slit across the screen instead of fullscreen helps the framerate considerably. I suspect that a lot of people use blackbars because higher FPS helps them, instead they could use the blackbars along the top and bottom of their screen and get the best of both worlds. Thanks to Sam Belliveau for suggesting the second method to me!

How do astronomers make sense out of the vastness of space? How do they study things so far away? Today Phil talks about distances, going back to early astronomy. Ancient Greeks were able to find the size of the Earth, and from that the distance to and the sizes of the Moon and Sun. Once the Earth/Sun distance was found, parallax was used to find the distance to nearby stars, and that was bootstrapped using brightness to determine the distances to much farther stars. -- Table of Contents Ancient Greeks Finding the Size of the Earth 1:07 Earth/Sun Distance Began Our Use of Parallax 5:39 Brightness Relation to Distance 9:07 -- PBS Digital Studios: http://youtube.com/pbsdigitalstudios Follow Phil on Twitter: https://twitter.com/badastronomer Want to find Crash Course elsewhere on the internet?

If you want to try this experiment, instructions are here: link.springer.com/article/10.1007/s12650-016-0383-5 The standard theory of quantum mechanics leaves a bit to be desired. As Richard Feynman put it, "I think I can safely say that no one understands quantum mechanics." This is because observations of experiments have led us to a theory that contradicts common sense. The wave function contains all the information that is knowable about a particle, yet it can only be used to calculate probabilities of where a particle will likely turn up. It can't give us an actual account of where the particle went or where it will be at some later time. Some have suggested that this theory is incomplete. Maybe something is going on beneath the radar of standard quantum theory and somehow producing the appearance of randomness and uncertainty without actually being random or uncertain. Theories of this sort are called hidden variable theories because they propose entities that aren't observable. One such theory is pilot wave theory, first proposed by de Broglie, but later developed by Bohm. The idea here is that a particle oscillates, creating a wave. It then interacts with the wave and this complex interaction determines its motion. Experiments using silicone oil droplets on a vibrating bath provide a remarkable physical realization of pilot wave theories. They give us a physical picture of what the quantum world might look like if this is what's going on - and this theory is still deterministic. The particle is never in two places at once and there is no randomness. Edited by Robert Dahlem Sound design by A Shell in the Pit

Radars are fantastic geospatial sensors and nowadays, they are actually quite affordable for general perimeter surveillance. However, radars lack the ability to give a visual identification to allow the operator to determine if this is a good guy or a bad guy. However, if you combine the radar with a geo-referenced PTZ camera a good portion of this can be done automatically. Just like the fence & camera example, the radar hands off the target information to the geospatial VMS, its presented as bearing & range, but is easily converted to latitude & longitude. It can even provide speed for fast moving targets, allowing the camera to automatically center the object in its field of view for ID. The radar can then continue to provide the camera location information for repointing, as show in this video. You can see each time the camera re-centers after it is given new data from the radar.

How to run this? + It needs cvBlobsLib. For setup info, get here: http://dsynflo.blogspot.com/2010/02/cvblobskib-with-opencv-installation.html Here's code for my test using cvblobs: http://dl.dropbox.com/u/110310945/Blobs%20test.rar + Distance between two cameras in my project is 6 cm, you can chose father distance for the best result with your camera's type + Before running "Detect objects & compute distance to object" module, you must calibrate your cameras. How? Change "#define CALIBRATION 0" to "#define CALIBRATION 1" in stdafx.h file. After calibration, you will get new matrices in "CalibFile" folder (*.yml), if the result is good enough, change back "#define CALIBRATION 0" Put this line into file stdafx.h: "#define ANALYSIS_MODE 1" as well. + I used chessboard 10x7 & 40 frames for calibration module, more details in "StereoFunctions.cpp" file. You can change these numbers suitable with your type of chessboard. + For problems with loading cameras, you should modify in "StereoGrabber.cpp". Put "index" appropriate with your device in cvCaptureFromCAM(index) function. + About computing distance: it interpolates the relationship between depth-value and real-distance to third degree polynomial. So i used excel file "interpolation" for interpolation to find k1 to k4, you should find your own value of these parameters. + For the best result, you should adjust parameters in Stereo Controls window. + This package includes matlab files in "Distance" folder, feel free to edit it. + For the basic theory, read this paper (also include his full code): http://scholar.lib.vt.edu/theses/available/etd-12232009-222118/unrestricted/Short_NJ_T_2009.pdf i used VS2008 with OpenCV2.1 for this project.

Support Our Channel : https://www.patreon.com/PeriscopeFilm Made in 1945 just after WWII ended, TARGET INVISIBLE was produced by the First Motion Picture Unit and features actor Clayton Moore (best known as 'The Lone Ranger') at the end speaking about war bonds. The film follows a squadron of bombers from their base in the Marianas through their mission over Tokyo. Particular emphasis is given on the use of radar for guidance to the target. At this time radar was fairly new and prized as one of the Allies' high tech weapons, and the film explains how it was instrumental in winning the war. At the end of the short, an announcer tells the audience that, while the war is over, Americans can now help win the peace sponsoring science through buying bonds. Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar transmits radio waves or microwaves that reflect from any object in their path. A receive radar, which is typically the same system as the transmit radar, receives and processes these reflected waves to determine properties of the object(s). Radar was secretly developed by several nations in the period before and during World War II. The term RADAR was coined in 1940 by the United States Navy as an acronym for RAdio Detection And Ranging. The term radar has since entered English and other languages as a common noun, losing all capitalization.

Current deep space telescopes do not provide a comprehensive picture of all objects in orbit around the Earth. Existing search telescopes have relatively narrow fields of view and cannot reliably detect and track faint objects, including small objects in geosynchronous orbits (roughly 22,000 miles high). There may be as many as hundreds of thousands of additional pieces of debris and asteroids that are too faint to track with current sensors. The Space Surveillance Telescope program aims to enable ground-based, broad-area search, detection, and tracking of faint objects in deep space for purposes such as space mission assurance and asteroid detection. SST offers improvements in determining the orbits of newly discovered objects and provides rapid observations of events that may only occur over a relatively short period of time, like a supernova.

She was a pageant girl who had already garnered six prestigious titles. This included Little Miss Colorado, America's Royale Miss and Little Miss Charlevoix, among others. With her blonde hair, blue eyes and gorgeous smile she had a bright future ahead of her. JonBenét's parents were a wealthy couple living in Boulder Colorado. Her dad, John was a multi-millionaire businessman and her mother, Patricia, was a socialite and former beauty queen herself. Both parents were fond of their daughter and provided her everything she could ever need in their luxury plush home. It was 5:45 AM when Patsy Ramsey called 911 weeping and distraught, saying that her daughter, JonBenét had been kidnapped. Within 7 minutes, the first responders were already at the home. John led the officers inside into the kitchen where on the table was a three-page handwritten note from the supposed kidnapper. #2 Black Triangle UFO's Since the early 80s, sightings of mysterious black triangle ships in the sky have been reported all over the world. These mysterious crafts are just as described - they have a triangle shape and are made from black or dark metal with flashing lights underneath. Among the first sightings of this type of UFO are those reportedly seen in Hudson Valley. It was 1983 when residents in the Hudson Valley of New York, reported a large craft fly over the area. (some say it was the size of a house and others reported it being as big as a football field) The craft had a distinct boomerang or triangular shape and had flashing lights on its underside. Witnesses also noted that it was made from a gunmetal or grayish color material. More than 5,000 people claimed seeing the huge ship and this included ordinary civilians, scientists and police officers. It was completely silent and slow moving and everyone was overwhelmed at the sheer size of it. Police were baffled when calls started coming in about the craft. Moreover, many estimate the ship was flying low at around 500-800 feet above the ground. The nearby Bradley International Airport neither confirmed nor denied the existence of the craft but said that if they had anything on radar it was most likely a weather balloon. However, most of the residents and witnesses aren't buying that explanation.

See the expanded and updated version of this show on... http://www.youtube.com/watch?v=PxG66QMd4wE The search for Earth-like planets is reaching a fever-pitch. Does the evidence so far help shed light on the ancient question: Is the galaxy filled with life, or is Earth just a beautiful, lonely aberration? If things dont work out on this planet Or if our itch to explore becomes unbearable at some point in the future Astronomers have recently found out what kind of galactic real estate might be available to us. Well have to develop advanced transport to land there, 20 light years away. The question right now: is it worth the trip? If things don't work out on this planet... Or if our itch to explore becomes unbearable at some point in the future... Astronomers have recently found out what kind of galactic real estate might be available to us. We'll have to develop advanced transport to land there, 20 light years away.... But that's for later. The question right now: is it worth the trip? The destination is a star that you can't see with your naked eye, in the southern constellation Libra, called Gliese 581. Identified over 40 years ago by the German astronomer Wilhelm Gliese, it's a red dwarf with 31% of the Sun's mass... and only 1.3% of its luminosity. Until recently, the so-called M Stars like Gliese 581 flew below the radar of planet hunters. They give off so little energy that a planet would have to orbit dangerously close just to get enough heat. Now, these unlikely realms are beginning to show some promise... as their dim light yields to precision technologies... ...as well as supercomputers... honed in the battle to understand global changes on this planet... Earth. Will we now begin to detect signs of alien life? Or will these worlds, and the galaxy itself, turn out to be lifeless... and Earth, just a beautiful, lonely aberration? To some, like astronomer and author Carl Sagan, the sheer number and diversity of stars makes it, as he said, "far more likely that the universe is brimming over with life." This so-called "many worlds" view can be traced back to ancient observers... in China, India, Greece and Egypt. The Qur'an, the Talmud, and many Hindu texts all imagined a universe full of living beings. In the 16th Century, this view got a boost from astronomer and mathematician Nikolas Copernicus... who came to believe that Earth is not the center of the universe, but revolves around the Sun. Seven decades after Copernicus, Galileo Galilei used his newly developed telescope to show that our Sun was just one among countless other stars in the universe. By the modern era, the "many worlds" view held sway in scientific circles. A variety of thinkers considered what and who inhabited worlds beyond our own. From Martians desperate to get off their planet... to alien invaders intent on launching pre-emptive strikes against ours... or simple life forms on an evolutionary track to complexity. But other thinkers have been struck by a different view. The Greek philosophers Aristotle and Ptolemy believed that humans and Earth are unique. With the spread of Christianity, this Ptolemaic system became widely accepted. The latest variation on this theme is what's called the "Rare Earth" hypothesis. It holds that Earth and sophisticated life were the result of fortuitous circumstances that may not be easy to find again in our galaxy. Does the current search for planets shed light on this debate... sending it in one direction or the other? So far, our only good reference for recognizing an Earth-like planet is... Earth. It does have some fortuitous characteristics... it's dense, it's rocky -- with a complex make-up of minerals and organic compounds -- and it has lots and lots of water. It's also got a nearly circular orbit around the Sun, at a distance that allows liquid water to flow... not too close and not too far away, in the so-called "Habitable Zone." That's defined as the range of distance from a parent star that a planet would need to maintain surface temperatures between the freezing and boiling points of water. Of course, that depends on the size of the planet, the make-up of its atmosphere, and a host of other factors. And whether the parent star is large; medium like the Sun; or small. Some scientists also believe we live in a "Galactic Habitable Zone." We're close enough to the galactic center to be infused with heavy elements generated by countless stellar explosions over the eons... But far enough away from deadly gamma radiation that roars out of the center. If there is a galactic habitable zone... it's thought to lie 26,000 light years from the center... about where we are... give or take about 6,000 light years.

Most cameras just record colour but now the 3D shapes of objects, captured through only a single lens, can be accurately estimated using new software developed by UCL computer scientists. The method, published at CVPR 2017, gives state-of-the-art results and works with existing photos, allowing any camera to map the depth for every pixel it captures. The technology has a wide variety of applications, from augmented reality in computer games and apps, to robot interaction, and self-driving cars. Historical images and videos can also be analysed by the software, which is useful for reconstruction of incidents or to automatically convert 2D films into immersive 3D. Inferring object-range from a simple image by using real-time software has a whole host of potential uses. Depth mapping is critical for self-driving cars to avoid collisions, for example. Currently, car manufacturers use a combination of laser-scanners and/or radar sensors, which have limitations. They all use cameras too, but the individual cameras couldn’t provide meaningful depth information. The new software was developed using machine learning methods and has been trained and tested in outdoor and urban environments. It successfully estimates depths for thin structures such as street signs and poles, as well as people and cars, and quickly predicts a dense depth map for each 512 x 256 pixel image, running at over 25 frames per second. Currently, depth mapping systems rely on bulky binocular stereo rigs or a single camera paired with a laser or light-pattern projector that don’t work well outdoors because objects move too fast and sunlight dwarfs the projected patterns. There are other machine-learning based systems also seeking to get depth from single photographs, but those are trained in different ways, with some needing elusive high-quality depth information. The new technology doesn’t need real-life depth datasets, and outperforms all the other systems. Once trained, it runs in the field by processing one normal single-lens photo after another. Understanding the shape of a scene from a single image is a fundamental problem. A 360 degree depth map would be fantastically useful – it could drive wearable tech to assist disabled people with navigation, or to map real-life locations for virtual reality gaming, for example. At the moment, the software requires a desktop computer to process individual images, but they plan on miniaturising it, so it can be run on hand-held devices such as phones and tablets, making it more accessible to app developers. It has also optimised only for outdoor use, so the next step is to train it on indoor environments. The team has patented the technology for commercial use through UCL Business, but has made the code free for academic use. Funding for the research was kindly provided by the Engineering and Physical Sciences Research Council.

Collisions with the walls and other cars while parking or unparking the car or while reversing the car is a very common problem that we all face in our everyday life. The situation becomes worse with crowd. Not only this , people also get engaged in arguments and conflicts disrupting social peace and harmony. To rectify the above problem, we have made a system that will map your surrounding showing the position of obstacles and will also give an idea of the size of the obstacle. In this project, we are using an ultrasonic Distance sensor. It generates sound waves beyond the scope of human hearing and measures distance by calculating the time required by these waves to hit an obstacle and travel back. This is similar to the principle used by bats. Another component that we are going to use is a servo motor. It differs from the usual DC motor in that it can turn very precisely to a given angular position and hold its state there. When a servo motor is given pulses of a specific duration, it moves to the corresponding angular position. We will be using both these components to get a 180° field of view. After the system gets the reading from the surrounding using the sensor and the motor , it will create a polar plot or map of the surrounding showing the position of different objects in the field of view of our system .

Surveillance and visual tracking of ground targets using Unmanned Air Systems (UAS) is challenging when the camera is strapdown, or fixed to the airframe without a pan-and-tilt capability, rather than gimbaled, so that the vehicle must be steered to orient the camera field of view. Visual tracking is even more difficult when the target follows an unpredictable path. This video demonstrates a machine learning algorithm for visual tracking of stationary and moving ground targets by UAS with non-gimbaling, fixed pan-and-tilt cameras. The algorithm is based on Q-learning, and the agent determines a control policy for vehicle orientation and flight path such that a target can be tracked in the image frame of the camera without the need for operator input. Performance of the system is demonstrated with flight test cases of stationary, randomly moving targets, and randomly moving targets in unstructured environments.

There are almost 30,000 man-made objects orbiting Earth. Many are tiny pieces of rockets and satellites, while others are completely dead satellites not in use anymore. All of them pose risks to other spacecraft and satellites — and as access to space becomes more affordable, the risk of a chain reaction of satellites crashing into one another will continue to increase.

This talk explains how radars are built and how they work. Have you ever wondered how a spectrum analyzer works, how to properly adjust all of the analyzer's parameters, or why a stair-step pattern initially appears on a spectrum analyzer screen when you turn it on? Do you know how to precisely calculate the analyzer's sensitivity in your head, merely by glancing at the screen display without any signal present? Are you uncertain about how much gain, and how low a noise figure, you ought to specify when you are ordering a low-noise amplifier (LNA) for a radio receiver? Do you want to know the difference between noise figure and noise factor? Do you wonder how to diagnose and solve radio interference problems? If you have questions about how to make good radio spectrum measurements or how to diagnose interference problems, you will find the answers in the NTIA Seminar Series on Spectrum Measurement Theory and Techniques. In this series of talks, an NTIA engineer at the Institute for Telecommunication Sciences (ITS) laboratory in Boulder, CO, discusses the fundamentals of radio spectrum measurements. The speaker, Frank Sanders, who has nearly thirty years of experience in this field, recognizes that even for many engineers who routinely use spectrum analyzers, the fundamentals of how they work and how to use them may be a bit murky; even in university lab classes the instructors do not always understand these machines very well themselves. Most of the talks, which are 80-100 minutes long, are divided into two parts. In the first portion of each video, Sanders explores a particular aspect of radio spectrum measurement technique or theory with a whiteboard lecture. In the second part, the lessons of the whiteboard discussion are implemented with actual measurement hardware and radio signals. A few of the talks, which for example involve large numbers of photographs of radar systems, are videos of his Microsoft Powerpoint presentations. In this series, Sanders explains spectrum analyzer functionality in terms of convolution bandwidth and shows how, when convolution is understood along with the mechanics of analyzer design, spectrum analyzer operations and outputs become easy to understand and use. Other topics include (1) what you need to know to use spectrum analyzers to examine all types of radio signals, including mobile radios, radars, and digital data links; (2) the use of low noise amplifiers and how to specify the right gain and noise figure for your receiver and measurement applications; (3) how radar systems work, and how to understand and interpret the signals that you see coming from radars; (4) the ways that radio interference can occur; (5) a methodical approach for diagnosing and solving radio interference problems; (6) the math needed to convert spectrum analyzer measurements into field strengths of radio signals; and (7) the proper conversions for radiation hazard calculations.

To listen to more of Freeman Dyson’s stories, go to the playlist: https://www.youtube.com/playlist?list=PLVV0r6CmEsFzDA6mtmKQEgWfcIu49J4nN American-British physicist and mathematician, Freeman Dyson, was born in England in 1923. Aged 25, he relocated to Cornell University and has become known for his achievements in the fields of solid state physics, nuclear engineering and quantum field theory. [Listener: Sam Schweber] TRANSCRIPT: One of the main reasons I came from England to America was because at the time when I made the decision all the good experiments were being done in America. I mean England was pretty barren as far as experimental physics was concerned, and then the main centre for the experimental work in America was Columbia. There was the physics department at Columbia; the leading spirit was Rabi who was a wonderful character and a great experimenter, and in Rabi's lab the decisive experiments were being done using the techniques of microwave spectroscopy that had been developed in World War II. So it was a spin-off essentially from the radar developments in World War II. All this microwave technology was available, and with microwaves you could observe very much finer details of atoms than you could before just with visible light. So, in particular, hydrogen, which is the thing that physicists love to play with, it is the simplest atom - you can do the spectrum of hydrogen with visible light, that had been done in the 1930s, and at that time they observed, there was a kind of suggestion, that things weren't quite right. The observed spectrum of hydrogen wasn't quite exactly what Dirac predicted it to be, but the difference was not quite clear because visible light isn't precise enough. But after the war when you had the microwave techniques you could measure the hydrogen spectrum really precisely, and that's what Lamb did. Willis Lamb, who was at Columbia working with Rabi, measured the hydrogen spectrum for the first time with really high precision with microwaves and he found this discrepancy between theory and experiment which is called the Lamb shift. Which was quite clear and definite with microwaves and you could measure it very accurately. So it became an outstanding problem for everybody to explain this. The hydrogen atom being the simplest and most deeply explored object in the whole universe, in a way - I mean if you don't understand the hydrogen atom, you don't understand anything, and to find that things were wrong even with a hydrogen atom was a big shock. So it became the ambition of every theoretical physicist to understand this. And basically that's why I came to America. I knew that's where the experiments were done, that's where I was likely to be able to really to get in touch with what was happening in the real world. And of course the people at Cornell were very closely in touch with the people in Columbia, and in particular Willis Lamb talked to Hans Bethe who was the professor at Cornell, and Bethe then sat down and gave the first more or less adequate theory of the Lamb shift, just from a physical point of view. He understood that the reason why you had the Lamb shift was that the electron in the hydrogen atom was interacting with the Maxwell electromagnetic field, in addition to interacting with the proton, so that the effect of the fluctuations in the Maxwell field were disturbing the electron while it was revolving around the proton, causing a slight change in the position of the orbits. And so it was the back reaction of the electromagnetic field on the electron that Lamb had been measuring. And so Bethe understood that from a physical point of view. The problem was then, could you actually calculate it? And with the quantum electrodynamics as it was then, it turned out you couldn't; that if you just applied the rules of the game as they were then understood and tried to calculate the Lamb shift, the answer came out infinity, not a number of megacycles but an infinite number of megacycles. So that wasn't very useful and so it was clearly a real defect of the theory that it couldn't grapple with this problem. And Hans Bethe in the spring of '47 succeeded in fudging it; by cutting off the Maxwell field at the high frequencies and considering only the low frequencies, he managed to get the right answer more or less. [SS] By doing mass renormalisation? Yes. He renormalised the mass, which means to say that he allowed for the fact that the measured mass of the electron already includes the back reaction of the Maxwell field, and so what you're comparing is not a bare electron and an interacting electron; you're comparing an interacting free electron with an interacting bound electron. So you have the interaction in both the bound and the free electron, so you're comparing the two states of an electron... Read the full transcript at http://www.webofstories.com/play/freeman.dyson/64
Over the last 2 months me and my friend Artem (you met him in the last video) built our first radio telescope. It was built mostly out of off the shelf components, like a satellite dish and Ku band LNB, as well as some parts we 3d printed. When all was said and done we had a system that could not only take images of the sky in radip frequencies (in this case 10-12ghz), but could also be used to track satellites. With it, we were able to see the ring of satellites in geosynchronous orbit, over 35,000km away, This is only the first of what I suspect will be many more telescopes like this. Next time we'll be building ones that are far larger and can see things like the hydrogen lines so we can image the milky way.

Current depth sensors (LIDARs, Kinect, stereo cameras, etc.) are expensive, power hungry and often demand dedicated hardware, cooling systems and precise calibration. On top of this, further processing needs to be done to get a velocity profile of the objects being sensed. In this work, we have developed an Ultrasound-Doppler Radar to investigate the application of Doppler Effect and Time-of-Flight to simultaneously estimate the speed and location of targets in a 360 degree horizontal field of view around a circular array of ultrasound piezoelectric transducers. The array consists of 8 pairs of ultrasound loudspeakers and receivers. To improve the spatial angular resolution and the framerate of our sensing, we employ offline loudspeaker and microphone beamforming. The time-delay and Doppler stretch factors (indicating the position and velocity respectively) are estimated together each frame. The device is low form-factor, inexpensive, low power consuming and enables a variety of interesting applications for indoor and outdoor, stationary and mobile Robotics sensing and Human-Computer-Interaction.

The Heisenberg uncertainty principle is just one specific example of a much more general, relatable, non-quantum phenomenon. Brought to you by you: http://3b1b.co/uncertainty-thanks And by Art of Problem Solving: http://aops.com/3b1b For more on quantum mechanical wave functions, I highly recommend this video by udiprod: https://youtu.be/p7bzE1E5PMY Minute physics on special relativity: https://youtu.be/1rLWVZVWfdY Main video on the Fourier transform https://youtu.be/spUNpyF58BY Louis de Broglie thesis: http://aflb.ensmp.fr/LDB-oeuvres/De_Broglie_Kracklauer.pdf More on Doppler radar: Radar basics: https://www.eetimes.com/document.asp?doc_id=1278808 There's a key way in which the description I gave of the trade-off in Doppler radar differs from reality. Since the speed of light is so drastically greater than the speed of things being detected, the Fourier representation for pulse echoes of different objects would almost certainly overlap unless it was played for a very long time. In effect, this is what happens, since one does not send out a single pulse, but a whole bunch of evenly spaced pulses as some pulse repetition frequency (or PRF). This means the Fourier representation of all those pulses together can actually be quite sharp. Assuming a large number of such pulses, it will look like several vertical lines spaced out by the PRF. As long as the pulses are far enough apart that the echoes of multiple objects on the field from different targets don't overlap, it's not a problem for position determinations that the full sequence of pulses occupies such a long duration. However, the trade-off now comes in choosing the right PRF. See the above article for more information.

Video of the near Earth Asteroid Today! Sorry the video isn't the greatest! Like trailers for the coming attraction, new images show asteroid 2012 DA14 on its way to a record-close approach to Earth on Feb. 15. One image, taken by amateur astronomer Dave Herald of Murrumbateman, Australia, on Feb. 13, shows the asteroid as a tiny white dot in the field of view. Another set of animated images, obtained by the Faulkes Telescope South in Siding Springs, Australia, on Feb. 14, and animated by the Remanzacco Observatory in Italy, shows the asteroid as a bright spot moving across the night sky. These are some of many images that may be taken of the asteroid during its close - but safe - encounter with Earth. It will be observed by numerous optical observatories worldwide in an attempt to determine its rough shape, spin rate and composition. NASA scientists will use NASA's Goldstone Solar System Radar, located in California's Mojave Desert, to take radar images of the asteroid to determine its precise size and shape on Feb. 16, 18, 19 and 20. The NASA Near Earth Object Observation (NEOO) Program will continue to track the asteroid and predict its future orbit. Asteroid 2012 DA14 is about 150 feet (45 meters) in diameter. It is expected to fly about 17,200 miles (27,000 kilometers) above Earth's surface at the time of closest approach, which is about 11:25 a.m. PST (2:25 p.m. EST) on Feb. 15. This distance is well away from Earth and the swarm of low Earth-orbiting satellites, including the International Space Station, but it is inside the belt of satellites in geostationary orbit (about 22,200 miles, or 35,800 kilometers, above Earth's surface.) The flyby of 2012 DA14 is the closest-ever predicted approach to Earth for an object this large. The NASA Near Earth Object Observation (NEOO) Program detects and tracks asteroids and comets passing close to Earth using ground- and space-based telescopes. The network of projects supported by this program, commonly called "Spaceguard," discovers these objects, characterizes a subset of them and plots their orbits to determine if any could be potentially hazardous to our planet. The Near-Earth Object Program Office at JPL manages the technical and scientific activities for NASA's Near-Earth Object Observation Program of the Science Mission Directorate in Washington. JPL is a division of the California Institute of Technology in Pasadena. The NEOO Program Office performs more precise orbit determination on the objects, and predicts whether any will become an impact hazard to the Earth, or any other planet in the solar system.

NASA's Europa Clipper will conduct detailed reconnaissance of Jupiter's moon Europa and investigate whether the icy moon could harbor conditions suitable for life. The mission will place a spacecraft in orbit around Jupiter in order to perform a detailed investigation of Europa -- a world that shows strong evidence for an ocean of liquid water beneath its icy crust and which could host conditions favorable for life. The mission will send a highly capable, radiation-tolerant spacecraft into a long, looping orbit around Jupiter to perform repeated close flybys of the icy moon. NASA has selected nine science instruments for the mission. The selected payload includes cameras and spectrometers to produce high-resolution images of Europa's surface and determine its composition. An ice penetrating radar will determine the thickness of the moon's icy shell and search for subsurface lakes similar to those beneath Antarctica's ice sheet. The mission will also carry a magnetometer to measure the strength and direction of the moon's magnetic field, which will allow scientists to determine the depth and salinity of its ocean. Gravity measurements will also help confirm the existence of Europa's subsurface ocean. A thermal instrument will survey Europa's frozen surface in search of recent eruptions of warmer water at or near the surface, while additional instruments will search for evidence of water and tiny particles in the moon's thin atmosphere. NASA's Hubble Space Telescope observed water vapor above the south polar region of Europa in 2012, providing potential evidence of water plumes. If the plumes' existence is confirmed -- and they're linked to a subsurface ocean -- studying their composition will help scientists investigate the chemical makeup of Europa's potentially habitable environment while minimizing the need to drill through layers of ice. During the nominal mission, the spacecraft will perform 45 flybys of Europa at closest-approach altitudes varying from 2700 kilometers to 25 kilometers above the surface.

The LASCO coronagraphs are very sensitive to dust particles that pass through the field of view. This is similar to the effect of a sunbeam shining through a window and scattering from the minute dust particles suspended in the air. Similarly, very small particles, at small angles from the Sun, get illuminated by the bright sun and are easily seen. Usually the space environment is very clean, but sometimes a streak is observed. Even more rare are images with multiple streaks, indicating more than one particle. The width of the streaks vary because the particles are at varying distances from the instrument. Since the instrument is focused for infinity the particles appear out of focus and thus broad. This can be used to determine how far away the particle is, assuming that the particle is otherwise very small. The length of the streak depends upon how fast the particle is moving, and how far it is from the instrument. For a given speed, the closer the particle is, the longer the track. Where do the particles come from? Some of them are obviously from the spacecraft. For example, the image on Jan 14, 1998 shows tracks that seem to emanate from a point. We believe that something must have hit the spacecraft and we see a shower of particles from the impact. But most of the images just show one or possibly 2 tracks. We believe that these are the interplanetary dust particles. Some images show particle tracks with different directions or radiants.

Space surveillance accomplishes the following: Predict when and where a decaying space object will re-enter the Earth's atmosphere; Prevent a returning space object, which to radar looks like a missile, from triggering a false alarm in missile-attack warning sensors of the U.S. and other countries; Chart the present position of space objects and plot their anticipated orbital paths; Detect new man-made objects in space; Correctly map objects travelling in the Earth's orbit; Produce a running catalog of man-made space objects; Determine which country owns a re-entering space object; Inform NASA whether or not objects may interfere with satellites and International Space Station orbits.The SPACETRACK program represents a worldwide Space Surveillance Network (SSN) of dedicated, collateral, and contributing electro-optical, passive radio frequency (RF) and radar sensors. The SSN is tasked to provide space object cataloging and identification, satellite attack warning, timely notification to U.S. forces of satellite fly-over, space treaty monitoring, and scientific and technical intelligence gathering. The continued increase in satellite and orbital debris populations, as well as the increasing diversity in launch trajectories, non-standard orbits, and geosynchronous altitudes, necessitates continued modernization of the SSN to meet existing and future requirements and ensure their cost-effective supportability.SPACETRACK also developed the systems interfaces necessary for the command and control, targeting, and damage assessment of a potential future U.S. anti-satellite weapon (ASAT) system. There is an Image Information Processing Center and Supercomputing facility at the Air Force Maui Optical Station (AMOS). The resources and responsibility for the HAVE STARE Radar System development were transferred to SPACETRACK from an intelligence program per Congressional direction in FY93.

Tesla Motors: Radar Mechanics Explained! Autopilot/Autonomous Radar -------- Lately, we've seen a lot of Impressive improvements from Tesla's Autopilot System. One major component of this system is the Radar. Because of this radar sensor, we're getting Impressive accident avoidance & Driver assistance features. I thought , why not dig deeper into this amazing, tiny, piece of hardware. One of my viewers was able to dig up the Bosh Manufacturers features & Specs paper. So lets take a look at this critical component. -Manufactured by Bosch. 1: Sensor is Multimodal with 4 independent receive channels and digital beam forming. Summed up, all this allows the sensor to be configured with independent antenna for different directions, improved accuracy, and adjustable “Field of View” depending on the situation. By focusing the radar at a narrow main lobe, with a angle of +/- 6*, the system can react to vehicles of long range, and perform well at higher speeds, as well as minimize interference from vehicles in adjacent lanes. Elevation Antenna with a +/- 42* opening, achieves a close range detection zone. Capable of detecting a pedestrian stepping out into the road from behind a parked car (As example) as a early stage detection. Due to the high level of integration of sensor and control functionality, Bosch was able to achieve compact design allowing ease of placement in a wide range of vehicle designs. Equipped with a self calibration system, the sensor searches for reference points on it's first Journey and calculates sensor axis deviation from dynamic driving axis. System software then compensates for this deviation during this learning phase. Some features or Functions may be disabled until complete. Solid state components, or in other words, no mechanical moving parts, allows the unit to have a high tolerance for vibration. Radome heating is available (Of which my investigations show Tesla to have Chosen). Radome heating allows the unit to melt off slush, ice and snow that is in direct contact with the unit. The Radar uses Frequency band of 76-77 Ghz. Due to Trippe-Carrier frequency, at 77Ghz, the sensor only needs 1/3 the antenna surface of other/older existing 24ghz sensors to cover the same field of view a the same resolution. Operation: Radar is designed to detect objects and measure their speed and position relative to movement of the vehicle of which it is fitted. To do this 1) Radar sends a radar wave in the 76-77Ghz range via Transmission Antennas; 2) Waves are reflected by objects in front of vehicle. 3) Relative speed and distance between the vehicle and other objects is determined based on the Doppler effect and the delay. Frequency shifts between sent and received signals are generated, and comparing the amplitude and phases of the radar signal measured by the four antenna, it is possible to infer the position of the object. Elevation antenna can generate an additional upward elevation beam allowing the sensor to measure the height of all detected objects, to help reliably classify relevant objects and determine if a vehicle can drive under or over them. Special signal processing algorithms are used. This allows the system to cope with complex traffic situations and brake more reliability, even in the case of stationary objects. Predictive Emergency Braking is also available! If “PEB” determines the distance to the preceding vehicle is becoming critically short, at a vehicle speed above 18mph (Hense the 18mph speed minimum for TACC and Autopilot); it will prepare the vehicle for potential emergency braking. If the driver does not react, the system uses Audible/Visual warnings, followed by a brake jerk. The system initiates partial braking, and if driver also applies brakes, it will calculate the pressure required to stop and apply additional force to avoid collision. If PEB detects unavoidable collision and operator does not intervene, it can in conjunction with a video camera (Autopilot camera) initiate full braking. If collision is unavoidable, even with AEB, it will do it's best to mitigate the severity of the collision. The sensor is capable of supporting TACC up to 93mph (150kph)(And in Tesla's case, Autopilot) with a max relitive speed of 50mph (80kph) and works in stop and go environments. Heading distance indicator can warn a driver is safe following distance is not being maintained. Sensor Data Fusion! This combines the benefits of different sensors and measuring principals in the most effective way possible. Providing data that individual sensors working on their own would be unable to generate. This “Fusion” increases the measurement range, reliability and accuracy. Video sensors along with software algorithms are data fused with the radar in Tesla autopilot This Fusion also allows for “AEB” pedestrian protection. ►https://www.facebook.com/KmanAuto ►https://www.YouTube.com/KmanAuto ►http://www.SuperchargerTravel.com [email protected] 414-807-8354

Many distances, like the distance around the earth, are impossible to measure directly. Yet almost 2,000 years ago, a man named Eratosthenes, was able to measure the size of the earth by using his knowledge of geometry. Today, surveyors use their knowledge of the properties of triangles to measure indirectly the distance between points on the earth's surface. The same method can be used to find the distance to nearby objects in space, by viewing the object from two different positions. If we know an object's distance, and how much of our field of view it takes up (its angular diameter) geometry also enables us to calculate the object's size.

This talk explains how to overcome the difficulties of measuring radar emissions. Have you ever wondered how a spectrum analyzer works, how to properly adjust all of the analyzer's parameters, or why a stair-step pattern initially appears on a spectrum analyzer screen when you turn it on? Do you know how to precisely calculate the analyzer's sensitivity in your head, merely by glancing at the screen display without any signal present? Are you uncertain about how much gain, and how low a noise figure, you ought to specify when you are ordering a low-noise amplifier (LNA) for a radio receiver? Do you want to know the difference between noise figure and noise factor? Do you wonder how to diagnose and solve radio interference problems? If you have questions about how to make good radio spectrum measurements or how to diagnose interference problems, you will find the answers in the NTIA Seminar Series on Spectrum Measurement Theory and Techniques. In this series of talks, an NTIA engineer at the Institute for Telecommunication Sciences (ITS) laboratory in Boulder, CO, discusses the fundamentals of radio spectrum measurements. The speaker, Frank Sanders, who has nearly thirty years of experience in this field, recognizes that even for many engineers who routinely use spectrum analyzers, the fundamentals of how they work and how to use them may be a bit murky; even in university lab classes the instructors do not always understand these machines very well themselves. Most of the talks, which are 80-100 minutes long, are divided into two parts. In the first portion of each video, Sanders explores a particular aspect of radio spectrum measurement technique or theory with a whiteboard lecture. In the second part, the lessons of the whiteboard discussion are implemented with actual measurement hardware and radio signals. A few of the talks, which for example involve large numbers of photographs of radar systems, are videos of his Microsoft Powerpoint presentations. In this series, Sanders explains spectrum analyzer functionality in terms of convolution bandwidth and shows how, when convolution is understood along with the mechanics of analyzer design, spectrum analyzer operations and outputs become easy to understand and use. Other topics include (1) what you need to know to use spectrum analyzers to examine all types of radio signals, including mobile radios, radars, and digital data links; (2) the use of low noise amplifiers and how to specify the right gain and noise figure for your receiver and measurement applications; (3) how radar systems work, and how to understand and interpret the signals that you see coming from radars; (4) the ways that radio interference can occur; (5) a methodical approach for diagnosing and solving radio interference problems; (6) the math needed to convert spectrum analyzer measurements into field strengths of radio signals; and (7) the proper conversions for radiation hazard calculations.

Here are some of the applications of Ground Penetrating Radar GPR can determine accurate depth and location of rebar, post tension cables, electrical conduit or plastic lines with in or beneath the concrete slab. GPR can locate piles, beams and other thickness changes in your foundation or slab. GPR can pin point voids or soil disturbances such as buried trenches below the slab. GPR can be used to accurately locate in floor heating lines eliminating costly strikes. GPR is not harmful or destructive and only requires being on one side of the slab. It utilizes high frequency light waves to produce a 3D view in real time of objects or voids within or under a surface. PCD or "Power Cable Detection" mode can be used to see current flow. This function is extremely useful when locating electrical conduit in a busy area.

DARPA Gives Air Force One Big Space Scope This week, DARPA officially handed over the keys to its 90-ton Space Surveillance Telescope (SST) to the U.S. Air Force Space Command. The Air Force plans to move the telescope from its perch high atop a mountain at White Sands Missile Range in New Mexico to Australia, where it will operate it jointly with the Australian government. DARPA built and designed the SST and according to the agency, it is redefining what telescopes are capable of, and could revolutionize space situational awareness. For example, SST uses the most steeply curved primary telescope mirror ever made. That allows it to collect more light to see images across a wider field of view. The scope’s camera is also unique, because it has the first-ever curved chargecoupled device, which provides clear imagery across the wide field of view. It also has the fastest shutter speed in the world and can take thousands of pictures a night. From its new home in Australia, SST will provide space situational awareness information from an area that is sparsely observed, but it will also provide surveillance data on transient events such as supernovas, as well as potentially hazardous near-Earth asteroids. According to Darpa, before the SST, it was like looking at a few large objects through a drinking straw. Now, it’s a windshield view that can see 10,000 objects at a time, from 22,000 miles away, each as small as a softball. Tap That Pipeline Researchers at the University of British Columbia have developed a simple vibration test that could help oil and gas companies prevent pipeline spills. The study found that pipeline imperfections could be identified by "tapping" the side of a pipe and then measuring the vibrations against computer models. According to the researchers, using these small “tapping” machines that are attached to above-ground pipelines is a much faster and cheaper way to find cracks or rust patches than traditional imaging techniques. The "tap test" theory actually stems from previous work with human bones. Turns out that the "tap test" was equally useful in finding areas of deficient bone density, which could be used to help identify conditions such as osteoporosis. Thorvald, God of Robotic Agri-Tech Thorvald is a mobile robot that they plan to use for new agri-tech experiments at the Lincoln Institute for Agri-food Technology (LIAT). Thorvald was designed in collaboration with scientists at the Norwegian University of Life Sciences, but the development is far from over. Researchers in Lincoln plan to first make the robot autonomous, so it can wander around fields and monitor crops and soils, moisture and fertility, and maybe even help farmers manage crops and precision weed control. They also plan to deploy a new COSMOS sensor, or COsmic-ray Soil Moisture Observing System. A new state-of-the-art moisture sensor to help grid moisture patterns, which is the most difficult thing for farmers to measure. Thorvald could be one of the key innovations for future farming, supporting research on everything from autonomous outdoor navigation and mapping, to crop yield prediction, in-field logistics and transportation. This is Engineering By Design with David Mantey.

2005 YU-55 is going to make a very close approach to the Earth on the night of November 8, 2011. At that time, its distance from Earth will be just under nine-tenths of the moon's distance away from us. 2005 YU-55 cannot hit Earth at least over the interval that we can compute the motion reliably which extends for several hundred years. It's going to be moving very rapidly as it traverses the sky near the Earth on November 7, 8, 9 and 10th. In affect it'll be moving straight at us from one direction and then it will go whizzing by and straight away from us in the other direction. So its motion across the sky will be close to degrees over the course of less than two days. It made a close approach to Earth about eighteen months ago in April of 2010. Colleagues of ours at Arecibo Observatory where able to observe this asteroid using the radar facility at Arecibo and they were able to obtain radar images that showed that this object is about 400 meters across. On November 8, 9, 10 we'll be observing it again. This time with both the Arecibo telescope and with the Goldstone telescope here in California. This is the closest approach by an asteroid that large that we've ever known about in advance. The radar telescopes that we use to observe asteroids are very large radio dishes. The Goldstone telescope is 70 meters, which is 240 feet across so it's truly enormous, and Arecibo is even larger still. The Goldstone telescope has a new radar imaging capability which has just become available that will enable us to see much finer detail than has previously been possible. And depending on how we transmit the signal we can get different types of data. It shows us how big it is, it can show us features on the asteroid, it can tell us information about the asteroids rotation period. We should be able to tell much better with these new observations that we're going to do. NASA Jet Propulsion Laboratory, California Institute of Technology

Working in the field of visual artificial intelligence, Cortexica is helping machines to see as well as we do; Steve Hemsley finds out more It was often a challenge for Cortexica to get other businesses to truly understand what it does. The company is an expert in vision artificial intelligence technology, which replicates elements of the human visual cortex, the part of the brain that processes visual information from the retina. Making sense of images has been something that, until recently, has stumped machines, but innovative developments in how systems ‘see’ and what they should look for are unlocking exciting areas of opportunity for many businesses, with companies such as Cortexica well-placed to take the lead in this field. The company was spun out from the Bioengineering department of Imperial College London ten years ago, and was named one of the “Cool Vendors for AI in Computer Vision”, by technology research giant Gartner earlier this year – a list that suggests not only an exciting business that’s flying under many people’s radar, but an entire sector. Yet in recent years Cortexica has really begun to get noticed, and it is now thriving, working with clients in sectors such as retail, manufacturing and health and safety. Fashion retailers, for example, have multiple applications for AI and image recognition. Whether its in-store or online, AI can analyse how people view a piece of clothing and how someone looks at its colour, shape, pattern and design. The results can improve customer experience and engagement, as well as improve operational decisions around category and stock management, merchandising and product image tagging. Applying Vision AI today Cortexica first recognised the potential of processing footage from cameras and live video streams in 2010, when it provided image and video recognition technology in real time to Virgin Money, as part of a brand-tracking exercise for that year’s London Marathon. It has since created a centre of excellence for video research and innovation to help companies in different industries identify what lies within images and what can be done with that information. CEO Iain McCready joined the business in March 2011, with more than 30 years of telecoms and IT industry experience behind him. He says that in the early days people didn’t ‘get’ what the company did. “They recognised the technology as cutting edge, but they did not want to pay for it” he says. “We are now working with shopping centre giants Hammerson PLC and partnering with the likes of Cisco and GSK. This has contributed towards our turnover increasing by 200 per cent in the past year.” It also seems as though the sky isn’t quite the limit for Cortexica, as they have recently been awarded a grant from the UK Space Agency to develop on-board processing of satellite imagery and video data. One of the growth areas for Cortexica is in the health and safety sector. For instance, its technology can identify whether people are wearing the right safety clothing and equipment before they are allowed into a restricted area. “We are now seeing clients from various sectors coming to us because they have heard that AI could help them, even if they are not quite sure exactly how,” says McCready. Cortexica has increased its workforce from 20 to 50 in the past two years by expanding its research and development, sales and marketing and client services teams. “We have spent the early years getting the product right, but these are the crucial areas we need to invest in to take the business to the next level.” Statistics Company website: http://www.cortexica.com Business sector: AI Vision HQ Location: London Number of employees: 50 Year founded: 2009
