摘要：
In this paper, a new direction of arrival (DOA) estimation algorithm is proposed when uncorrelated and coherent wideband signals coexist. The proposed method estimates the uncorrelated signals and coherent signals respectively at two different stages. It makes the method resolve more sources than the array elements. Compared with the coherent signal subspace method (CSSM), the proposed method does not require any initial DOA estimates, thus avoid errors brought by incorrect initial values. Simulation and experimental results validate the effectiveness of the proposed algorithm.
