摘要: This paper addresses the synthesis of three-dimensional (3D) radiation patterns time-modulated conformal arrays. Due to nature periodic time modulation, harmonic are generated at multiples modulation frequency in Thus, optimization goal array includes sidelobe level operating and sideband levels (SBLs) frequency, design can be regarded as a multiobjective problem. The particle swarm (MOPSO) is applied optimize switch-on instants pulse durations array. To significantly reduce variables, modified Bernstein polynomial employed process. Furthermore, dual polarized patch antenna designed radiator achieve low cross-polarization during beam scanning. A 12 × 13 (156)-element conical microstrip simulated demonstrate proposed mechanism, good results reveal promising ability algorithm solving arrays
