最近，[多方等人]已经表明在双基地多输入多输出（MIMO）雷达中，ESPRIT算法如何利用发射阵列和接收阵列的不变性特性进行目标方向估计。然而，这种方法在每个维度分别估计发射角和接收角，然后需要在二维角度估计之间进行配对匹配，这需要额外的计算量。在这项报道的工作中，利用两个一维ESPRIT之间的相互关系，在不降低双基地MIMO雷达角度估计性能的情况下，自动获得配对的发射角和接收角估计。给出了仿真结果以验证所提方法的有效性。
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.
