Synthesis of robust beamforming weights in linear antenna arrays

An innovative method for the synthesis of robust beam-forming weights of linear antenna arrays is presented in this work. Starting from user-defined mask power constraints, the configuration of the amplitude weights is optimized by means of a hybrid tool integrating the Interval Analysis (IA) and the Particle Swarm Optimization (PSO) in order to maximize the resilience of the weight coefficients with respect to possible tolerances while guaranteeing the satisfaction of the given constraints on the arising power pattern. A representative result is reported and discussed to show the behavior of the proposed approach and its specificity in comparison with other techniques already presented in the state-of-the-art literature.
