Direction of Departure (DOD) and Direction of Arrival Estimation in Bistatic MIMO Radar Using Covariance Recovery of Sparse Targets

This letter propose a new method based on covariance sparse target recovery for Direction of Departure (DOD) and Direction of Arrival (DOA) in bistatic multi -input multi-output radar. The letter use this property that the number of target in the space is low. In this paper we recover the power of incident signal as a diagonal matrix which its diagonal element are corresponding to the impinging signals. We show that our method doesn’t need the number of sources and also it is independent from the coherency between the signals. Simulation results demonstrate the effectiveness of our algorithm compared with other methods. KeywordsMIMO, Radar, DOA and DOD ,Sparse.
