说明：  这是采用esprit算法、music算法和MINnorm算法实现目标一维角度测量。输入为多接收阵元接收的回波信号，代码可直接采用matlab语言使用
(This is to use ESPRIT algorithm, music algorithm and minnorm algorithm to achieve one-dimensional angle measurement. The input is the echo signal received by multiple receiving elements, and the code can be directly used in MATLAB language)
