ABSTRACT:
A method of estimating the directions of radiating sources (56, 58, 60) with respect to an array (46) of a number of antenna elements (48), each of which elements has a separate gain/phase control (50). With nominal gain and phase selected a first estimte of the radiating sources directions (.theta.) is accompished by application of the MUSIC algorithm (2). The algorithm is iteratively applied to a microprocessor (54) using updated gain and phase values. Iteration is terminated at that iteration which produces the maximum difference values of the smallest eigenvalue pair of Q.sub.(i).
