摘　　要：干扰材料及烟幕是对抗精确制导武器最主要的无源干扰手段,是当前新一代无源干扰技术领域的研究热点;干扰材料、发烟装备、器材的发展离不开理论指导、科学试验和评价结果的支撑;从干扰效能评价方法和电磁波吸收的基本定律两个方面对干扰材料及烟幕干扰效能评价领域的研究现状、存在的主要问题和发展趋势进行了系统分析;指出目前3种主要的干扰效能评价方法对干扰材料、发烟装备、器材的发展提供了重要支撑;分析表明当前研究存在质量消光系数计算公式合理性存疑的问题,结合朗伯-比尔定律的推导得出了修正后的烟幕质量消光系数计算方法,使质量消光系数的计算结果更加精确;提出了烟幕中质量消光系数仅适用于均匀非散射烟幕体系这一限制条件,并提出了实现多种烟幕干扰效能评价结果相互验证的发展趋势。As the most important passive jamming means against precision guided weapons, jamming materials and smoke screens are the research focus of the new generation passive jamming technology. The development of jamming materials and smoking equipment highly relies on theoretical guidance, scientific tests and evaluation results. This study systematically analyzes the current status, problems and prospects of the shielding performance evaluation of jamming materials and smoke screens from two aspects: the shielding performance evaluation method and the basic law of electromagnetic wave absorption. The results show that the current three main shielding performance evaluation methods provide important support for the development of jamming materials and smoking equipment. The analysis shows that the rationality of the calculation formula of the mass extinction coefficient is questionable. Combined with the deduction of Lambert-Beer’s law, this paper obtains the revised calculation of the smoke screen mass extinction coefficient, which makes the calculation result more accurate. This paper puts forward the limiting condition that the mass extinction coefficient in smoke screens is only applicable to uniform nonscattering smoke screen systems, and the development trend that mutual verification of various smoke screen shielding performance evaluation results is realized.
