Abstract
A microstrip antenna radiates and receives six beams in sequence out of a common aperture and processes return signals with common electronics in order to measure the velocity components relating to a backscattering surface. Sequentially, the first four beams are processed by measuring Doppler shift in a return signal while the last two beams are processed for time correlation. The result of the present invention is a combined time correlation and Doppler measurement velocity sensor available for operation over virtually all terrains and the vehicle speed range.
