Abstract
As a result of solution of the optimization problem, a new method for estimating the amplitude-phase distribution in multielement antenna arrays is proposed and studied by numerical simulation. The method is based on calculating the principal eigenvector of the spatial correlation matrix and increases the efficiency of classical and super-resolution methods for the spatial localization of a priori unknown broadband signals.
