A novel beamspace ESPRIT (B-ESPRIT) algorithm is proposed to estimate the direction of departures (DODs) and direction of arrivals (DOAs) for bistatic MIMO radar. It restores the rotational invariance structure lost in the beamspace transformation for both the transmit array and the receive array, and then the DODs and DOAs can be estimated through ESPRIT. The proposed algorithm can achieve a significant computational saving over the element-space ESPRIT (E-ESPRIT) algorithm for bistatic MIMO radar. Simulation results validate these conclusions.
