Researchers at the Georgia Tech Research Institute recently combined machine learning, field-programmable gate arrays (FPGAs), graphics processing units (GPUs), and a novel radio frequency image ...

The basic principle of radar systems is simple enough: send a radio signal out, and measure the time it takes for a reflection to return. Given the abundant sources of RF signals – television signals, ...

BBB Cycling has launched the Signal Radar rearview radar/tail light. It’s priced competitively, at £119.99, and includes a speaker, so you don’t need a separate device to alert you when a vehicle is ...

Let’s start off with proof. Below is an animation of a measurement of airplanes and meteors I made using a radar system that I built with a few simple easily available pieces of hardware: two $8 RTL ...

As Pentagon officials delay approval of wind farms, scientific studies show that they can distort radar systems, but the ...

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.

Saab's new Ultra-Lightweight Camouflage Screen (ULCAS) is a net that allows soldiers to hide from radar sweeps, while still being able to receive GPS signals and radio communications. For over a ...
