中文说明：在读研究生期间，写过的基于music时延估计的虚拟阵程序，包括以下几部分内容：加入强度不同的噪声，构成矩阵，在频域music估计。加入不同强度的不同噪声，构成矩阵，在频域music估计。用三个回波作为输入信号以及多频域music时延估计。
English Description：
When I was a graduate student, I wrote a virtual matrix program based on music time delay estimation, which includes the following parts: adding noise of different intensity to form a matrix, and estimating music in frequency domain. Different noises with different intensities are added to form a matrix, which is used to estimate music in frequency domain. Three echoes are used as input signals and multi frequency domain music time delay estimation.
