基于天线阵列协方差矩阵的特征分解类DOA估计算法中，MUSIC算法具有普遍的适用性，只要已知天线阵的布阵形式，无论是直线阵还是圆阵，不管阵元是否等间隔分布，都可以得到高分辨的估计结果。-DOA estimation algorithm, MUSIC algorithm has universal applicability of decomposition classes based on the characteristics of the antenna array covariance matrix, known lineup in the form of the antenna array, linear array and circular array, regardless of the elements whether such as interval distribution, estimation result of a high resolution can be obtained.
