DOD and DOA tracking algorithm for bistatic MIMO radar using PASTD without additional angles pairing

In this paper, we mainly discuss projection approximation and subspace tracking of deflation(PASTd) for direction of departure (DOD) and direction of arrival (DOA) tracking multiple targets in bistatic multiple-input multiple-output (MIMO) radar. The research on DOD and DOA tracking of moving targets in bistatic MIMO radar has been reported rarely. This proposed algorithm can obtain signal subspace by PASTd without computing eigen-value decomposition of the cross correlation matrix or singular value decomposition of the received data, which reduces much computational load, it also can get DOD and DOA paired without additional consideration in bistatic MIMO radar. Simulation results verify the usefulness of our algorithm in tracking moving targets.
