To reduce the number of array elements and improve the directions of arrival estimation accuracy for the coherence multi-path incident signal.A new method for directions of arrival estimation is proposed,in which frequency domain independent component analysis and null beamforming are combined.The array of structural information and statistical independence properties of the target signal is used to the proposed method,compared wite the conventional algorithm the dependence on the number of array and the accuracy of the array manifold are reduced,and the coherence multi-path incident signal DOA estimation is achieved.Computer simulation results show that the algorithm has a small array elements,fast convergence and small error characteristics.
