中文说明：用空间平滑music算法和奇异值分解算法来分别估计相干信号的DOA。设两个相干信号的角度分别为-20°和40°，当用以上两种方法估计时比较信号的频谱，观察-20度和40°处有冲击响应强度及带宽从而比较出两种方法的精度。
English Description：
Using spatial smoothing MUSIC algorithm and singular value decomposition algorithm to estimate the DOA of coherent signals, respectively. Design two coherent signal angle respectively 20 and 40 degrees, when using the above two methods to estimate when comparison signal spectrum observed - 20 degrees and 40 degrees impact response intensity and bandwidth so as to compare the accuracy of the two methods.
