说明：  music算法条件是在阵列采用8阵元的均匀线阵，阵元间距为半波长，期望信号的信噪比为10dB，方向为0度，干扰号的干噪比为20dB，方向为25度，并且期望信号和干扰信号间是不相干的，快拍数为512。
(With the proviso that the array 8 array element uniform linear array, the array element spacing of a half wavelength, the desired signal to noise ratio is 10dB, the direction is 0 degrees, the number of interference noise ratio 20dB, and a direction of 25 degrees, and it is desirable between the signal and the interference signal is irrelevant, the number of snapshots is 512.)
