提出了一种新的用于双基地MIMO雷达出发方向(DOD)和到达方向(DOA)联合估计的酉ESPRIT算法。利用中心厄米特矩阵的性质将复值数据矩阵变换为实值数据矩阵。然后推导出信号子空间的实值旋转不变性方程，以一种新的方式估计自动配对的DOA和DOD。该算法采用实值处理，提高了估计精度，降低了计算复杂度，使么正ESPRIT的数据样本数增加了一倍。仿真结果验证了该算法的有效性。
A new Unitary ESPRIT algorithm for joint direction of departure (DOD) and direction of arrival (DOA) estimation in bistatic MIMO radar is proposed. The properties of centro-Hermitian matrices are utilised to transform the complex-valued data matrix into a real-valued data matrix. Then the real-valued rotational invariance equations for signal subsapce are figured out to estimate DOAs and DODs which are paired automatically in a new way. The proposed algorithm provides increased estimation accuracy with reduced computational complexity owing to real-valued processing and double the number of data samples inherently in unitary ESPRIT. Simulation results are presented to verify the effectiveness of the proposed algorithm.
