First flight for MP-RTIP equipped Global Hawk (Photo: Northrop Grumman)

Northrop Grumman's Block 40 Global Hawk has new eyes. The unmanned aircraft completed its first full system flight carrying the production version of the next-gen Multi-Platform Radar Technology Insertion Program (MP-RTIP) sensor at Edwards Air Force Base, California, on July 21.  Read More

Nancy Sinatra once mused that her boots were made for walking. In these days of global positioning, going walkabout is not as random an event as it might once have been, but there are still occasions when the all-seeing GPS device can't pick up a satellite. In such cases, having a back-up could mean the difference between getting out of the deep, dark underground cave in one piece or being lost in its tunnels forever. Researchers from North Carolina State University and Carnegie Mellon University have combined technology that is used to measure speed and distance with portable radar equipment to help keep track of a user's location.  Read More

The new Space Fence will detect space debris that could threaten the ISS and commercial an...

There are tens of thousands of pieces of space debris currently orbiting the Earth which pose a potential hazard to satellites, the International Space Station and other space hardware. Since the early 1960s, the existing Air Force Space Surveillance System, also known as the VHF or Space Fence, has been used to track orbital objects passing over America. Proposals are now being taken for the next phase of a new Space Fence that will better detect, report and track orbiting space junk as well as commercial and military satellites.  Read More

The Russian T-50 PAK-FA fighter jet prototype taking its maiden flight

Russia has reportedly successfully test-flown its first fifth generation fighter jet prototype. Formally known as the Prospective Aircraft Complex of Frontline Aviation (PAK-FA), the craft made its 47 minute maiden voyage on 29th January. Manufactured by the Russian state owned Sukhoi Aircraft Corporation, the development of this tactical frontline stealth fighter jet is being seen as a significant milestone in the efforts of the country to modernize its post Soviet–era military technology.  Read More

PocketRadar's mini speed radar.

Speed radar technology has become pretty much ubiquitous for traffic law enforcement around the world, but there are times when you and I would quite like to know how fast something is travelling too. PocketRadar is a hand-held personal speed measurement device about the size of a mobile phone that can get you a speed reading on a car half a mile away (or a baseball 120 feet away) in less than a second from being fully shut down. It's initially targeted at sports fans and athletes, but the company has flagged the possibility of a law enforcement version as well.  Read More

A prototype of the 'stealth' blade developed by QinetiQ and Vestas is fitted onto a Vestas...

Plans for the installation of wind farms the world over are being delayed or abandoned due to objections from the aviation community or air defense interests. The problem is that when it comes to low flying aircraft or wind turbines, conventional radar has a bit of an identity crisis - not being able to tell the difference. Recent tests in the UK of "stealth" turbine technology could provide a solution.  Read More

ScanEagle UAV gets Synthetic Aperture Radar (SAR)

March 18, 2008 The ScanEagle UAV has proven a revelation in Iraq and Afghanistan, offering another key informational input on the battlefield to help soldiers under fire make better decisions. The bad news for enemies of the United States is that the miniature UAV can now carry Synthetic Aperture Radar (SAR) which can pick out man made objects not readily visible to IR or EO cameras.  Read More

Volvo City Safety

February 15, 2008 British Motor Insurance Repair Research Centre Thatcham has put three of the car industry’s most hyped collision prevention technologies to the test – and they’ve emerged with flying colors. The Volvo City Safety, Mercedes Distronic Plus, and Honda CMBS use radar systems to mitigate and prevent low speed collisions – which, as a category, make up 75% of all motor accidents.  Read More

Researchers explore the use of radar anti-landmine technology

August 31, 2007 There is perhaps no graver reminder of the indiscriminate cruelty of modern warfare than the landmine. It's estimated that over 100 million landmines remain concealed around the world and with the aim of improving detection techniques, researchers from the Delft University of Technology in the Netherlands are developing a ultra-wideband radar system that they hope will make the process safer and cheaper.  Read More

First UAV to use High-Resolution Synthetic Aperture Surveillance Radar

December 7, 2006 Lockheed Martin recently accomplished a first for unmanned aerial systems (UAS), demonstrating that high-resolution, broad-area imaging from a Miniaturized Synthetic Aperture Radar (MiniSAR) could effectively be delivered by a UAS into the hands of tactical unit commanders, regardless of smoke, dust, heavy rain or night-time conditions. During a successful field exercise at the Minnesota National Guard test facility on October 19, a small SkySpirit UAS carrying a Sandia-developed MiniSAR sensor soared to nearly 3,000 feet and, in near real-time, became the first UAS to successfully transmit four-inch resolution SAR imagery. During four different mission demonstrations, the SkySpirit transmitted MiniSAR images capturing actionable data in two operational modes: focused area circle-mapping and broad area strip-mapping. Multiple imaging passes were post-processed to demonstrate coherent change detection used to identify changes over time.  Read More
