Central DOA Estimation Method for Exponential-Type Coherent Distributed Source Based on Fourth-Order Cumulant
The performance of direction-of-arrival (DOA) estimation for sparse arrays applied to the distributed source is worse than that applied to the point source model. In this paper, we introduce the coprime array with a large array aperture into the DOA estimation algorithm of the exponential-type coher...
