Abstract
A vehicle velocity sensing system is disclosed which includes a doppler velocity sensor (10, 12) and means for reducing spurious signal components in the output of the sensor. An accelerometer (30, 32) is mounted so as to sense vehicle accelerations along the boresight of the doppler velocity sensor. A processor (34, 36) processes the output of the accelerometer to provide a signal which corresponds essentially to the spurious components of the output of the doppler radar velocity sensor. A signal combiner (38, 40) combines the output of the processor with the output of the doppler velocity sensor to derive a corrected output signal which is more closely indicative of the velocity of the vehicle.
