摘要: 涂层结构设计是实现吸波涂层良好吸收性能的重要手段,利用计算机辅助进行结构设计成为研究趋势。针对当前涂层结构计算机辅助设计存在的运算效率低、优化目标单一、需人工干预等问题,构建了吸波涂层“宽、轻、薄、强”的多目标优化模型,设计了一种基于多目标遗传算法NSGA-Ⅱ的多层吸波涂层结构设计方法,给出了已知材料、已知涂层数下的最优涂层结构设计方案。经实际喷涂测试,采用3号和2号材料的双层吸波涂层经优化后的总厚度为0.6 mm,在18~18 GHz 波段的反射率均低于-8 dB. 试验验证表明,在保证一定预测冗余的情况下,该方法对雷达波吸收涂层的设计具有一定参考价值。

Abstract: The design of coating structure is an important method to achieve the favorable absorbing capability. For the issues in the computer-aided design of cpating structure, such as low operation efficiency, optimization of single target and manual intervention, a multi-objective optimization model of radar absorbing coating with the aim of “thin-layer, light-weight, broad-band and strong-absorbing” is constructed, and an optimized project based on NSGA-Ⅱis presented.The optimized thickness of the double-layer absorbing coating composing of 3# and 2# materials is 0.6 mm with the reflectance of lower than -8 dB at 18~18 GHz band. Experiments show that this method can be used for the structure design of multilayered radar absorbing coating in case of prediction of redundancy.
