Abstract: A fast estimation algorithm for Direction of Departure (DOD) and Direction of Arrival (DOA) in bistatic MIMO radar is proposed. This algorithm should be used in conjunction with an existing algorithm to perform the estimation. First, the DOD is estimated by an existing algorithm. Then the estimated DOD is used to divide the multi-objective model into many single-objective models. Finally, the DOA can be estimated quickly without Singular Value Decomposition (SVD) and peak search. Besides, no pair procedure needs to be implemented in this process. The main advantage of the proposed algorithm is that it can simplify the original algorithm and ensure the estimation accuracy. Simulation results demonstrate the validity of the proposed algorithm.
