A wideband beamforming algorithm for estimating the azimuth angle, elevation angle, velocity, and range using a planar phased radar array with antenna switching is proposed. It uses the time-variant steering vector model. Simulation results illustrating the performance of the proposed beamformer are presented. Recently, there has been great interest in the development of advanced radar systems with phased arrays. In traditional multichannel radar array systems, the number of receivers should be equal to the number of receiving antennas, so the hardware expense and power consumption are very high.
