摘要
Abstract
A novel algorithm,called B-ESPRIT,is proposed to localize the targets for bistatic MIMO radar.The proposed algorithm can restore the rotational invariance structure lost in the beamspace transfor-mation for both the transmit array and receive array,and then the direction of departures(DODs)and direc-tion of arrivals(DOAs)can be estimated through ESPRIT.Since it can reduce the dimension of the data after beamspace transformation,the proposed algorithm achieves a significant computational saving over the ele-ment-space ESPRIT(E-ESPRIT)algorithm for bistatic MIMO radar.Furthermore,the relationship between the beamformer matrix gain of the proposed algorithm and the angle of the target is discussed in detail.The correctness of the analysis is verified by the computer simulation results.关键词
