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.本研究报告给出改进music的实现步骤-Direction of Arrival (DOA) estimates the basic problem is to define the space at the same time in more than interested in a particular region of the spatial location of the signal (ie, multiple signals arrive at the array element reference to the direction of angle). The earliest and most classic super-resolution DOA estimation method is well-known MUSIC method. The present study is given to improve the realization of music steps
