A hybrid approach for the synthesis of square thinned arrays with low sidelobes is presented. The proposed method combines the advantages of a genetic algorithm and combinatorial technique-cyclic difference sets (CDSs). The peak sidelobe level (PSL) and the thinning factor are numerically evaluated to show the effectiveness and reliability of the proposed hybrid method. In the proposed GA-enhanced square arrays with the DS and the best CDS, reductions of the PSL, of 4.16dB and 2.45dB, respectively, were achieved as compared to the results of conventional rectangular DS and CDS arrays.
