英文摘要：

MATLAB is used to develop the system model of array signal processing, such as the correlated signals, the error of amplitude and phase. To deal with these different models, MATLAB offers great instructions and fuctions, which make the simulating considerably convenient. The key programs were proposed, which could simulate the covariance matrix estimation, estimate the DOA （direction of arrival） of signal based on subspace, calculate the weight vector of adaptive beamformer, and get some basic system parameters. Some examples show the detail procedure and the programs are useful to the array signal processing research. Furthermore, these methods take an important function to many other complicated simulations.
