摘要
Abstract
In this paper ,we propose an efficient direction of arrival estimation method for wideband coherent signals in the presence of correlated noise with uniform linear array .Firstly ,the component of correlated noise is eliminated by using the spatial differencing technique and then a new matrix is constructed by performing the squaring operation at each frequency bin .Afterwards , a universal covariance matrix is obtained by performing a focusing operation .Finally ,the coherent signals are resolved by applying the propagator method .The signal number in a coherent group resolved by the proposed method can be even or odd .Simulation re-sults demonstrate the effectiveness and performance of the proposed method .关键词
