How does police radar know which car is speeding?
RADAR. RADAR units use pulses of radio waves to determine the speed of a vehicle.As part of the ‘proper operating procedures’, the officer is supposed to visually estimate the speed of the target vehicle. The reading on the RADAR unit should correlate with that visual estimate.
