Abstract :
In this paper we describe a processing scheme for direction of arrival estimation using multichannel data in a broadcast digital television based passive radar system. We discuss the interrelationship between the clutter cancellation stage and the performance of the direction of arrival (DoA) estimation stage and show that imperfect knowledge of the reference signal leads to a non-uniform noise energy distribution in the spatial dimensions in the processing scheme employed.
