Wu Ying · Shengxue jishu · 2012
Beam-space transformation is an important preprocessing of direction of arrival(DOA),which fits for the large array and small source number situation and is able to reduce the computational complexity,but the ex-isting beam-space DOA algorithms need the approximate directions of signals and cannot fit for all array.In this paper a beam-space DOA algorithm based on independent component analysis ICA) is proposed to solve the above problems,the algorithm gets the beam-space transformation matrix using ICA and has high resolution,which has no request for array manifold and approximate directions of signals.Simulation result reveals that the proposed algorithm has good performance.
