Abstract :
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.
