Doa Estimation With Co-Prime Arrays In The Presence Of Mutual Coupling

In this paper. we present a method for performing direction -of-arrival (DOA) estimation using co-prime arrays in the presence of mutual coupling. The effects of mutual coupling are first examined for extended co-prime arrays configurations using the Receiving-Mutual-Impedance Method (RMIM). DOA estimation is then achieved by performing a joint estimation of the angles of arrival and the mutual coupling matrix, using the mixed-parameter covariance matrix adaptation evolution strategy. Simulation results demonstrating the effectiveness of the proposed method are provided.
