It was one of the most provocative findings of the past decade in planetary science: a potential underground lake of liquid water beneath Mars’ South Pole. First reported in 2018 by a team using the ...

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

Despite the excitement surrounding the radar signals, researchers caution that liquid water beneath Mars’ south polar ice would be difficult to maintain under the planet’s extreme cold. Without highly ...

"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 ...

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 ...

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.

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