Abstract

For coherent targets direction of arrival (DOA) estimation problem of MIMO radar, a DOA estimation algorithm for coherent targets of TR MIMO radar based on Toeplitz matrix method is proposed. Algorithm use TR theory according to the received signal model of MIMO radar to establish the received signal model of TR MIMO radar. Using Toeplitz matrix method based on the received signal model which removes the coherency of targets and utilizing an optimized iterative approach based on the first-order approximate theory that carries out DOA estimation further improve the estimation accuracy and reduce computation complexity. The results of computer simulation show that the proposed method has lower computation complexity and higher estimation accuracy compared with the conventional non-TR MIMO radar under the same snapshots and signal-to-noise ratio conditions.

Key words： DOA estimation; TR MIMO radar; Toeplitz matrix; optimized iterative approach; first-order approximate
