Abstract: To solve the problem of performance degradation of parameter estimation algorithms for coherently distributed non-circular sources under the impulsive noise environment, this paper proposes the concept of generalized complex correntropy and a new DOA estimation method based on generalized complex correntropy for coherently distributed non-circular sources. Firstly, the algorithm obtains an array output matrix of incident signal through the distributed source model, and constructs the extended array output by using the non-circular characteristic of the signal. Then the generalized complex correntropy matrix of the extended array output is used to get the signal subspace, which avoids the degradation problem of the traditional second-order statistic algorithm in the impulsive noise environment. And finally the central direction of arrival of the signal is obtained by the rotation of the signal subspace. The simulation results show that the proposed algorithm has better performance than the traditional algorithm under the condition of Alpha stable distributed noise.
