摘要(Abstract)：
针对当前吸波材料性能评价方法与雷达探测实际场景脱节、忽略多因素协同影响的不足，本研究旨在构建与雷达作用距离挂钩的评价体系，解决现有方法侧重单一参数、评价结果难贴合应用需求的问题；同时为吸波材料性能优化、涂层厚度设计提供量化依据，推动材料向“高性能+薄型化”发展，为其研发与应用提供科学评价支撑。为此，通过研究反射损耗、有效带宽和涂层厚度3个单因素对雷达吸波材料的影响，分析了电磁损耗模型、电磁匹配衰减模型和界面反射模型的优点及缺点。基于雷达作用距离方程，综合反射损耗、有效带宽和涂层厚度3个因素，利用matlab数值模拟建立了基于削减雷达作用距离的吸波材料性能评价方法。最后通过此评价方法对四氧化三铁/还原氧化石墨烯（Fe_3O_4/RGO）吸波材料进行了验证，其验证结果与实验结果吻合。该评价方法可为吸波材料的性能提升及涂层减薄发展提供参考。
