Abstract
A method for estimating a direction of arrival of a signal transmitted by a signal source and received by an antenna array. The method estimates the covariance matrix of the signals received by the antennas of the array and derives therefrom a direction of arrival. The received signals are correlated with a reference signal transmitted by the source prior to being submitted to the covariance matrix estimation.
