WebPolice radar transmits a radio wave in the microwave band that upon striking an object is reflected back to the radar gun and a “Doppler Shift” occurs in the frequency that is received back by the radar gun. The radar gun thus measures this change in frequency and then calculates the speed either in miles per hour or in kilometers per hour.

Web2 days ago · LIDAR detectors can detect the use of LIDAR guns to some degree, but their effectiveness is not as high.
