Abstract

 Computation complexity of spatial spectrum estimation algorithm is high. To solve this problem,a PM algorithm is introduced for estimation of 2D direction of departure (DOD) and 2D direction of arrival (DOA) for bistatic MIMO radar. A propagator is estimated using the cross correlation matrix. By rotationinvariance
of the propagator, one can estimate the direction of the matrix, and further estimate DOD and DOA. The algorithm has low computation complexity, and can achieve multi-dimensional automatic pairing. With similar angles, good performance is still maintained. In the case of high SNR, performance of the proposed algorithm is close to that of the ESPRIT. Mean square error of angle estimation is derived. Simulation results verify the usefulness of the algorithm.

Key words： multiple-input multiple-output (MIMO) radar; direction of departure (DOD); direction of arrival (DOA); automatic pairing; propagator method
