Recently, it has been shown [Duofang et al.] how the ESPRIT algorithm exploited the invariance property of both the transmit array and the receive array for target direction estimation in a bistatic MIMO radar. However, this method estimates the transmit angles and the receive angles separately in each dimension, and then requires pair matching between the two-dimensional angle estimation, which requires additional computational load. In this reported work, the interrelationship between the two one-dimensional ESPRIT is utilised to obtain automatically paired transmit angles and receive angle estimation without debasing the performance of angle estimation in a bistatic MIMO radar. Simulation results are presented to verify the effectiveness of the proposed method.
