| Abstract: | A high resolution DOA estimation method for coherent wide band sources based on outputs of constant beamwidth beams is proposed in this paper. Computer simulation results show that the algorithm in this paper obtained better performance than the coherent signal subspace algorithm and reduced the computation complexity. |
