Abstract EN
A multiobjective approach based on the third evolution step of generalized differential evolution (GDE3) algorithm is proposed for optimizing the time-modulated array (TMA) in this paper.
Different from the single-objective optimization, which optimizes a weighted sum of the peak sidelobe level (PSLL) and the peak sideband level (PSBL) of the array, the multiobjective algorithm treats the PSLL and the PSBL as two distinct objectives that are to be optimized simultaneously.
Furthermore, not only one outstanding optimization result can be acquired but also a set of solutions known as Pareto front is obtained by using the GDE3 algorithm, which will guide the design of time-modulated array more effectively.
Users can choose one appropriate outcome which has a suitable tradeoff between the PSLL and the PSBL.
This approach is illustrated through a time-modulated concentric circular ring array (CCRA).
The optimal parameters and the corresponding radiation patterns are presented at last.
Experimental results reveal that the multiobjective optimization can be an effective approach for the TMA synthesis problems.
