Two types of radar
WebPolice radar transmits radio waves at a fixed frequency. Some of the beam reflects from a target vehicle and returns to the radar. If the target is moving, a slight change in frequency occurs (Doppler shift). The radar does the heavy math and calculates target speed. How Police Radar is Used. Two types of radar are used—stationary and moving. WebFactors affecting radar performance.
