The direction of arrival estimation algorithm for low-angle targets with MIMO radar is discussed, and a novel peaks searching algorithm according to the multipath received signal model is derived. The proposed algorithm, which uses the multipath echo signal power and MIMO radar spatial diversity, can avoid the effects of complexmultipathtransmittervariable and targets glint. It is illustrated that the algorithm has a better performance with the increase of multipathvariable or the transmit antennas. Simulation results verify the usefulness of the algorithm.
