title: Peak Sidelobe Level Reduction with a Hybrid Approach based on Gas and Difference Sets
ispublished: pub
subjects: TU
full_text_status: public
keywords: Array antennas, massively thinned arrays, difference sets, genetic algorithms, side-lobe control
abstract: This paper presents an approach for the optimization of the beam pattern produced by massively thinned arrays. The method, which combines the most attractive features of a genetic algorithm and those of a combinatorial technique (namely, the Difference Sets Method), is aimed at synthesizing massively thinned antenna arrays in order to suitably reduce the peak side-lobe level. Selected numerical results are presented in order to assess the effectiveness and reliability of the proposed approach. (c) 2004 IEEE. Personal use of this material is permitted.
