摘　　要：为进一步研究武器装备的隐身问题,实现隐身涂层的合理设计,研究MAM反射系数的理论计算原理,并建立了适当的模型,作为设计、制备符合反射系数指标要求MAM涂层及其性能分析的基本依据。根据隐身技术的基本原理,在提出选择正确的电磁参数形式的同时,给出了避免复数运算的简便计算方法。通过分析MAM厚度与反射系数的关系,初步得出了微波吸收材料存在最佳吸收厚度的结论。In order to research the stealthy technique of arms and accomplish the proper design of stealthy coatings, the principle of theoretical arithmetic for the reflectance of MAM is discussed and the model is established in this paper, which will provide the bases for designing and preparing coatings that can satisfy the requirements of reflectance of MAM as well as analyzing effectiveness of the coatings. The way of selecting accurate electromagnetic parameters is put forward according to the principium; a simple method is given and adduced. By analyzing the relationship between thickness and reflectance of MAM, the optimum absorption thickness of MAM is proven to be in existence.
