Abstract：In order to solve the problem of low tracking performance for bistatic MIMO radar based on Adaptive Asymmetric Joint Diagonalization (AAJD) algorithm, an improved multi-target tracking method is proposed. The reason for the low tracking performance of AAJD algorithm is that the estimated angle of the previous time is reused for angle estimation. It is proved that each eigenvectors of the AAJD algorithm corresponds to a target. Improved AAJD algorithm can estimate the DOD and DOA directly, which improves tracking performance and can solve high maneuvering target tracking problems. And the ESPRIT algorithm is improved to realize the automatic matching and association of DOD and DOA. The simulation results show that the improved AAJD algorithm has higher tracking performance than AAJD algorithm, especially when the large maneuvering target is tracking. The efficiency of the proposed method is verified.
