Radar gun
A radar gun is a small Doppler radar used to detect the speed of objects. A radar gun does not return position or power information. It relies on the Doppler effect applied to a radar beam to measure the speed of objects it is pointed at.
Radar guns may be hand-held or vehicle-mounted. Common uses include traffic speed law enforcement, and measuring the speed of balls in sports.
