基于工程定制化的伪装吸波材料设计研究

为实现工程目标与不同背景融合要求,开展针对环境变化的吸波材料定制化设计方法及涂层配方研究。根据传输线理论,通过设置多变量参数,编制了基于衰减量可调的改进遗传算法设计程序,对比实测与模拟值结果,验证了该方法的可行性;在分析电磁参数对吸收峰影响规律基础上,研究提出了采用磁改性填料对反射率曲线定向调节的方法。结果表明,优化的涂层配方实现了在Ka波段的宽频吸收,亦降低了目标与背景的辐射温差对比,满足了涂覆目标在主被、动探测下兼容的要求,可用于工程目标的防雷达伪装。

Design of camouflage absorbing material based on engineering customization

In order to achieve the integration of engineering with different backgrounds,this paper presents a detail study on the customized design method and coating formulation of the absorbing materials under the environmental variation.According to the theory of transmission line,an improved genetic algorithm design program based on the adjustable attenuation was developed by setting multivariable parameters,and verified by comparing the measured value with the simulation results.Based on the analysis of the influence of electromagnetic parameters on absorption peak,a method of directional adjustment of the reflectivity curve with magnetic modified filler was proposed.The results show that the optimized coating formulation achieves broadband absorption in Ka band,as well as reduces the difference of the radiation temperature between the target and the background.The coated targets is compatible under the active-passive detection mode,which can be used for anti-radar camouflage of the engineering targets.
