Abstract
Traditional direction of arrival (DOA) estimation for a MIMO array assumes perfect knowledge of the array manifold. Its performance will degrade severely in the presence of array model errors. In this paper we propose a simple scheme for robust DOA estimation based on a MIMO array configuration, where two well-calibrated transmit sensors are used as the transmit array and no knowledge about the receive array manifold is assumed. Its performance is verified by simulation results.
