Abstract

A simple scheme for direction of arrival (DOA) estimation of coherent targets in a multiple-input multiple-output (MIMO) radar is proposed. It is based on the idea of joint transmission and reception diversity smoothing. Compared to the existing transmission diversity smoothing (TDS) method, the major advantage of the new scheme is that more covariance matrices are available for averaging to decorrelate the coherent signals, leading to a better estimation result. Moreover, it is able to identify much more coherent targets than the TDS method when sparse arrays are used.
