摘要
针对目前红外隐身涂料不能最大限度满足目标动态隐身需求以及没有合适的方法评估涂料隐身性能的问题,提出了一种隐身涂料性能优化与评估的方法。首先,以传热模型为基础,模拟计算了目标与背景的表面温度;然后,根据目标与背景的辐射对比度,对单一隐身涂料的发射率、短波和长波吸收率进行了优化设计;最后,定义了迷彩涂料隐身效能的评价参数,分析了多种红外迷彩涂料的隐身效能。研究结果表明:隐身涂料的性能参数经优化后有效提高了目标的隐身效率,从29.2%提高到79.2%;同时,隐身性能评价参数可以用来评估迷彩涂料的隐身效能。
According to the fact that the current infrared stealth coatings can not meet the requirement of dynamic stealth of target and there is no suitable means to evaluate these coatings＇ stealth performance, the method about optimization and evaluation of stealth performance of coatings was proposed. First, based on the heat transfer model, the surface temperature of target and background was calculated. Then, according to radiance contrast of target and background, the emissivity, longwave and shortwave absorptivity of single stealth coating were optimized. At last, evaluation parameters of camouflage coating were defined, and stealthy effectiveness of various camouflage coatings was analyzed. The results show that the stealthy efficiency increase rapidly （form 29.2% to 79.2%） after the optimization of single coating, and evaluation parameters of camouflage coating are useful in evaluating stealthy effectiveness.
