中文摘要：

提出一种基于双／多基地方位联合估计的新算法，利用两个阵列或多个阵列的接收数据的相关矩阵，再结合ESPRIT算法估计方位。该算法可以同时估计目标信号入射到双／多基地的方位角。所估计的参数自动配对，不需要额外的配对运算，并且给出了该方法方位估计的CRLB，计算机仿真结果证明了算法的有效性。

英文摘要：

A new approach was proposed for the DOAjoint estimation of signal, and the algorithms are based on ESPRIT and two or more array data correlation matrix. It estimated simultaneously the DOA of bis/multistatic. The algorithms estimated parameter are auto paired, The CRLB of the DOA stimafion was also derived, The simulating results show that the new methods are equally effective.
