数据相干分析的可信度，评价相干分析数值是否有意义-the confidence level of coherence

—The minimum variance distortionless response (MVDR) approach is very popular in array processing. It is also employed in spectral estimation where the Fourier matrix is used in the optimization process. First, we give a general form of the M
