After “some” RF design courses, he decided that he had learned enough to build his own frequency-modulated continuous wave radar system. From the level of detail on this project, we’d say ...

The main challenges addressed during the design stage were: Guided wave radar (GWR) or time domain reflectometry is a two-wire microwave level instrument that transmits a radar signal down a metallic ...

1940s radar relied on a semiconductor crystal, or "rectifier." Radar worked by sending out a radio wave and analyzing the reflected wave after it bounced off any objects in the air. The rectifier ...

What Is RADAR? Radio Detection and Ranging is a system or device that uses electromagnetic radio waves to determine the range, velocity, and angle of the objects in the surrounding area. This system ...
