Description: 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

Description: 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 Signal Classification）的英文缩写。它是由R．O． Schmidt于1979年提出来的，由1986年重新发表的。MUSIC算法利用了信号子空间和噪声子空间的正交性，构造空间谱函数，通过谱峰搜索，检测信号的DOA．(The basic problem of DOA estimation is to determine the location of multiple interested signals in a certain area at the same time, that is, the direction angle of multiple signals arriving at the array reference element. The earliest and the most classical super-resolution DOA estimation method is the famous MUSIC method, and MUSIC is the abbreviation of Multiple Signal Classification. It was proposed by R.O.Schmidt in 1979 and was republished in 1986. The MUSIC algorithm takes advantage of the orthogonality between the signal subspace and the noise subspace, and constructs the spatial spectral function. It detects the DOA. of the signal by spectral peak search.)
