Abstract :
An innovative methodology for the synthesis of sparse linear arrays with prescribed pattern features is numerically analyzed when dealing with large aperture layouts. The technique is based on a probabilistic formulation of the synthesis problem which is solved through a Bayesian Compressive Sensing (BCS) technique. A set of numerical experiments are presented to assess the features and potentialities of the BCS design approach when layouts comprising several hundred elements are at hand.
