The coherent DOA estimation of uniform circular array based on SVD algorithm

摘要

The SVD algorithm is an efficient method for the coherent DOA estimation, but it just fits only for the uniform linear array. A method of the coherent DOA estimation based on UCA is proposed in this paper. Through combining model-switching with SVD algorithm, it can improve the performance of decorrelation for uniform circular array. The computer simulations showed that this method has a good performance of decorrelation.
