Abstract: MATLAB is used to develop the system model of array signal processing.How to simulate the coveriance matrix estimation of forward-backward smoothing,siganl’s DOA(Dirction Of Arrival) estimation of subspace,the weight of minimum power beamformer and some basic system parameters are present in detail.All the other complicated simulation can be completed according to them.

Key words: array signal, covariance matrix, DOA, beamforming
