Abstract

The multilayer broadband radar absorber optimization problem (MBRAOP) is characterized as a mixed-variable multimodal multiobjective optimization problem (MVMMOP) in real-world applications. This paper proposes a novel approach called HEDA-DulMVMO to solve the MBRAOP. The method introduces an enhanced dual-population cooperative evolutionary mechanism to balance convergence and diversity in both the discrete decision space and the objective space. Additionally, the histogram-based estimation of distribution (EoD) model is employed to generate high-quality auxiliary evolutionary populations. The performance of the proposed approach is validated on the designed MVMMOP benchmark problems. Final optimization and evaluation are conducted on the multilayer broadband radar absorber (MBRA) for configurations ranging from 2 to 7 layers, with incident angles from 0°to 75°across five critical frequency bands. Experimental results on both the benchmark problems and the MBRA demonstrate the effectiveness and competitiveness of the proposed approach.

基于EoD学习的双种群协同进化机制优化MBRA设计

多层宽带雷达吸波器优化问题（MBRAOP）在实际应用中具有混合变量多模态多目标优化问题（MVMMOP）的特点。本文提出了一种新的方法HEDA-DulMVMO来解决MBRAOP问题。该方法引入了一种增强的双种群合作进化机制，以平衡离散决策空间和目标空间的收敛性和多样性。此外，采用基于直方图的分布估计（EoD）模型生成高质量的辅助进化种群。在设计的MVMMOP基准问题上验证了该方法的性能。最后对2 ~ 7层、5个关键频段入射角0 ~ 75°的多层宽带雷达吸收体（MBRA）进行了优化和评估。在基准问题和MBRA上的实验结果表明了该方法的有效性和竞争力。
