Optimal Synthesis of Shaped Beams Through Concentric Ring Isophoric Sparse Arrays

An innovative deterministic approach to the optimal power synthesis of mask-constrained shaped beams through the concentric-ring isophoric sparse arrays is presented. The design procedure exploits at best the state-of-the-art techniques, respectively, available in the cases of circular-ring isophoric arrays radiating pencil beams and of linear isophoric arrays generating shaped beams. The technique avoids the exploitation of global-optimization algorithms and allows us to significantly outperform all the (few) available procedures.
