中文说明：该程序适用于相干信号的DOA估计。用空间平滑music算法和奇异值分解算法（SVD）分别进行相干信号的DOA（信号到达角）估计，比较两种算法在相同信噪比条件下的分辨力。程序仿真时设置了角度为10°和20°，角度差还可以更小。
English Description：
The procedure is applicable to the DOA estimation of coherent signals. Using the spatial smoothing MUSIC algorithm and the singular value decomposition (SVD) algorithm to estimate the DOA (signal arrival angle) of coherent signals, the resolution of the two algorithms is compared under the same signal to noise ratio (SNR). When the program is simulated, the angle is 10 degrees and 20 degrees, and the angle difference is smaller.
