Abstract

An efficient direction of arrival (DOA) estimation method for wideband uncorrelated signals is presented in the presence of mutual coupling. The method first exploits the auxiliary elements to eliminate the influence of unknown mutual coupling. Then by using the concepts of the Khatri-Rao product and uniform focusing, the method gives the DOA estimates of wideband signals. Thus, the method is suitable to the case that the mutual coupling is unknown, and the case that the frequency spectrum of signals is flat. Moreover, the number of resolved signals can be more than that of the elements in some case. Simulation results confirm the effectiveness of the method.
