Abstract :
Many classical direction of arrival (DOA) estimation algorithms suffer from sensitivity to mutual coupling of antenna array. In this paper, a stable estimation method of DOA estimation is introduced. This method is applying a group of auxiliary arrays, exploiting the banded symmetric and Toeplitz matrix model for the mutual coupling in a uniform linear array (ULA), based on the estimation of signal parameter via rotational invariance techniques (ESPRIT) algorithm. The favorable DOA estimation can be provided without the knowledge of the array mutual coupling matrix. The correction and efficiency of the proposed algorithm are verified by the computer simulation results.
