Abstract :
A new direction of departure (DOD), direction of arrival (DOA) and Doppler frequency estimation algorithm for non-uniform bistatic Multiple-input multiple-output (MIMO) radar is proposed. The snapshots in a coherent processing interval (CPI) also form a non-uniform sequence. Based on tensor decomposition, the factor matrices corresponding to virtual uniform arrays and virtual uniform snapshot sequence are obtained for parameters estimation. The proposed improve method further reduces the error in a noise condition. Simulation results verify the effectiveness of the proposed algorithm.
