A New Compensation Method for the Mutual Coupling Effect in Wideband 2D Direction-of-Arrival Estimations

Abstract A new compensation method for the mutual coupling effect is proposed. This compensation method is based on the mutual coupling grid and transient mutual coupling coefficient proposed in this article. It can be used for antenna arrays composed of wire elements. The new compensation method is applicable for the 1D as well as 2D array signal processing. The new compensation method is employed in wideband 2D direction-of-arrival estimations. The numerical results verify the effectiveness of the new compensation method for wideband 2D direction-of-arrival estimations.
