DOD and DOA Estimation Algorithm in Bistatic MIMO Radar Based on Propagator Method
摘要
Abstract
Since multi-input multi-output (MIMO) radar uses multiple antennas to simultaneously transmit diverse waveforms and utilizes multiple antennas to receive the reflected signals, it has many potential advantages over conventional phased-array radar. A direction of departure (DOD) and direction of arrival (DOA) estimation algorithm is proposed in bistatic MIMO radar based on propagator method. This algorithm uses propagator method to reduce the computation, without eigenvalue decomposition on covariance matrix. At the low SNR and small snapshots, the algorithm has a good performance. Compared with the algorithm of fast multi-target localization, the angle estimation of the algorithm is improved. And we derived the mean square error of the DOD and DOA estimation. The simulation results demonstrate its effectiveness and robustness.关键词
