单次快拍 MUSIC 算法，这种单次快拍 MUSIC 算法仅利用接收的一次快拍的 M（M 为阵元数）个数据，通过对这 M 个数据做统计处理，来估计阵列数据的协方差矩阵(Single snapshot MUSIC algorithm, this single snapshot the MUSIC algorithm only receiving a snapshot M (M array element number) data, statistical treatment of these M data to estimate the array data co covariance matrix)

对于chebyshev法只能对于均匀线阵，本程序实现对任意结构阵列的波束优化(Chebyshev method for only the uniform linear array, the program structure of arbitrary beam array optimization)
