中文说明：matlab程序运行时导入数据文件作为输入参数，现代信号处理中谱估计在matlab中的使用，与理论分析结果相比，通过虚拟阵元进行DOA估计，使用大量的有限元法求解偏微分方程，模拟数据分析处理的过程。
English Description：
Matlab program is running into data files as input parameters, in modern signal processing spectral estimate in MATLAB is used, and theoretical analysis results are compared, through virtual array for DOA estimation, using a large number of finite element method for solving partial differential equations, simulation data analysis process.
