摘　　要：矢量传感器的阵信号处理是研究矢量阵工程化应用的重要内容,但其运算量大。针对这一问题,提出了一种矢量阵的改进MMUSIC算法,该方法将维纳滤波引入到MMUSIC算法中,避免了矩阵的特征值分解,降低了运算量。采用矢量传感器均匀线阵研究该算法的性能,进行了仿真研究和实验验证。计算机仿真和实验结果表明:提出的算法可以清晰分辨相干信号,其性能优于MMUSIC算法,从而验证了该算法的有效性和可行性。Processing the matrix signals of vector sensor is critical to the research on engineering application of vector matrix.However,such processing amount requires massive computation.Aiming at this problem,a new modified MUSIC algorithm（MMUSIC） based on vector matrix is introduced to solve such issue.The method reduces computation amount by applying the Wiener Filter in MUSIC algorithm to skip decomposition of eigenvalues.The method of vector sensor uniform linear array（ULA） is adopted to study the performance of the modified algorithm.The simulation and experiment verify the effectiveness of such new MMUSIC algorithm,showing that the new MMUSIC algorithm can clearly distinguish the coherent signals,and is superior to the original MMUSIC algorithm.
