Developed with the help of a team of China's PLA scientists, the stealth coating absorbs over 99.99 per cent of incident ...

In a breakthrough in radar technology, researchers from the City University of Hong Kong (CityUHK) have developed the world's ...

I crossed five states, dodged speed traps, and delivered Katz’s pastrami from New York to Michigan while it was still warm, all thanks to some trusty radar detectors.

"Our findings suggest that radar signals – produced unintentionally by any planet with advanced technology and complex aviation systems – could act as a universal sign of intelligent life." So, we're ...

Radar (acronym for Radio Detection and Ranging) uses radio waves to detect objects in the environment. It allows determining the distance (known as range), angular position (bearing), and velocity.

Two problems with conventional radar make it unsuitable for many applications: Anyone with a radar receiver can tell when you activate it, and it can't image objects closer than about 100 feet.

Multifunction radar systems have evolved to perform a host of tasks from surveillance to target tracking, realising complex electronic support measures with high precision. At the heart of these ...

Guided by the U.S. Army Research Laboratory, researchers from the Bradley Department of Electrical and Computer Engineering at Virginia Polytechnic Institute and State University are examining the ...

In January 2008, hundreds of people in Stephenville, Texas, reported seeing a massive silent craft—some described it as the ...
