提出一种高分辨方位估计新方法。它是建立在阵列输出信号和噪声参数联合后验概率密度基础上的空间谱估计。仿真结果表明，该方法具有以下几个显著的优点：①极高的空间分辨率和估计精度；②可解相干源；③低信噪比、少快拍数的情况下很有潜力；④可以估计不同方向目标源的能量；⑤具有较好的工程应用前景。该方法和ＭＵＳＩＣ方法的性能进行了比较并给出计算机仿真结果。
A new method of high resolution DOA estimation is proposed. It is based on the array output signal and noise parameters combined posterior probability density based on the spatial spectrum estimation. The simulation results show that this method has the following significant advantages: (1) very high spatial resolution and estimation accuracy; (2) resolvable coherent sources; (3) low signal-to-noise ratio Estimate the energy of the target source in different directions; ⑤ Have a good prospect of engineering application. The performance of this method and MUSIC method are compared and the computer simulation results are given.
