Synthesis of Sparse Concentric Ring Arrays With Minimum Element Spacing Control by Modified Two-Step Optimization Strategy

A modified two-step optimization strategy (MTSOS) is proposed for the synthesis of sparse concentric ring arrays (CRAs). The strategy adopts the discretizing-then-optimizing strategy, which can effectively reduce the error caused by discretization. In the first step of MTSOS, densely spaced concentr...
