Angle estimation of bistatic MIMO radar in the presence of unknown mutual coupling

In this paper, a new joint the direction of departures (DODs) and the direction of arrivals (DOAs) estimation method in the presence of unknown mutual coupling for bistatic multiple-input multiple-output radar (MIMO) radar is presented. By setting the auxiliary elements on the both sides of the transmit and arrays, the effect of mutual coupling can be eliminated and the standard MUSIC can be utilized directly to estimate the DODs and DOAs. Simulation shows that the proposed method can get better estimation performance than the standard MUSIC with unknown mutual coupling and can be close to the performance of the standard MUSIC with known mutual coupling in the high SNR.
