摘　　要：提出一种基于双基地频率和方位联合估计的新算法,是基于UN-ESPRIT方法和两个阵列之间的互相关DOA矩阵法,称之为UN-DOAa-ESPRIT算法。该算法可以同时估计目标信号的频率和两个基地(即两个阵列天线)方位角。所估计的参数自动配对,不需要额外的配对运算,而且在不知道的相关噪声环境下同样可以有效地进行估计。数值仿真结果证明了算法的有效性。A new approach is proposed for the DOA and frequency joint estimation of signal. This algorithm is based on UN-ESPRIT and DOA array algorithms of correlated data between two arrays, called UN-DOAa-ESPRIT algorithm. It estimates simultaneously the DOA of two array antenna and frequency. The estimated parameters are automatically paired, eliminating the need for additional paring computation and improving the robustness to spatially unknown correlated noise. The simulating results show that the new method is effective.
