{{more citations needed|date=August 2014}}Ground speed radar is a non-mechanical way of measuring the speed of a vehicle. The Speed sensor fires a radar beam towards the ground and measures the Doppler shift of the returning beam.[1] This information is then sent to the engine control unit which calculates the forward speed.
