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.

Radar and LiDAR are two key technologies for sensing the surrounding environment, widely used in industries such as automotive, robotics, security, and environmental monitoring. The fundamental ...

For as long as small, hidden radio transmitters have existed, people have wanted a technology to detect them. One of the more effective ways to find hidden electronics is the nonlinear junction ...
