Technology / Radar / Doppler Radar: A radar that detects and interprets the doppler effect in terms of the radial velocity of a target. The signal received by radar from a moving target differs in frequency from the transmitted frequency by an amount that is proportional to the radial component of the velocity relative to the radar gun. Example of doppler radar - decatur police radar guns. A lot of sports radar guns, such as bushnell velocity speed gun, are doppler radars as well.
