中文说明：MATLAB阵列信号处理经典算法源码波达方向（DOA）估计的基本问题就是确定同时处在空间某一区域内多个感兴趣的信号的空间位置（即多个信号到达阵列参考阵元的方向角）。最早的也是最经典的超分辨DOA估计方法是著名的MUSIC方法，MUSIC是多重信号分类（Multiple SignalClassification
English Description：
MATLAB array signal processing algorithm source code, direction of arrival (DOA) estimation of fundamental problems is to make sure that same space multiple signals of interest within a region of space where (that is, multiple signal reaches an array reference of array elements direction angle). Earliest and most classic of Super-resolution DOA estimation method is famous for its MUSIC, MUSIC is the multiple signal classification (Multiple SignalClassification) abbreviation. MUSIC algorithm using signal subspace noise-subspace of and the orthogonality of constructed spatial spectral function, and Times New Roman, detecting signal DOA. This provides is the classic algorithm of the source.
