Synthesis of flat-top power pattern in time-modulated unequally spaced linear arrays using DE

摘要: In several applications such as wireless communication, radar; shaped beam patterns are used to radiate power in a desired sector of region while suppressing the towards other direction avoid interferences. This paper introduces new technique synthesizing flat-top pattern time-modulated unequally spaced linear arrays (TMUSAs). Since, TMUSA synthesis problems multimodal, nonlinear type which cannot be solved using analytical techniques. Therefore, stochastically based searching and optimization differential evolution (DE) algorithm is applied optimize static excitation with low dynamic range ratio (DRR), element spacings on-time sequence simultaneously, order synthesize sidelobe suppressed sideband radiation satisfying requirements. The numerical result 30 TMUSLA shows superiority proposed respect conventional (CUSLA) previously patterns.
