Doppler radar information


U.S. Army soldier using a radar gun, an application of Doppler radar, to catch speeding violators.

A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance.[1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. The term applies to radar systems in many domains like aviation, police radar detectors, navigation, meteorology, etc.
