A three-channel weight perturbation spectrum estimate direction finding (DF) method is proposed in this paper.Firstly,the array covariance matrix is obtained by the weight perturbation algorithm.Then the eigen-structure based algorithm is employed to estimate the direction of arrivals.Coherent signals in correlated environment are coped with by spatial smoothing technique.The performance of the proposed method is evaluated by extensive simulations,and computer simulation results verify that the method provide more effective and robust estimation results.It offers a practical approach to direction finding in the case of fewer receivers being used.

Key words: three channel;DF;weight perturbation;spatial smoothing
