Abstract
A mutual coupling compensation method is proposed to enhance the estimation accuracy of an incident wave upon a uniform circular array (UCA), with the initial guess estimated using the UCA-rank reduction (RARE) method. Simulation results under various signal-to-noise ratios confirm the effectiveness of the proposed method.
