| 摘 要： | 根据雷达吸波材料厚度薄、质量轻、吸收频带宽、吸波能力强(薄、轻、宽、强)的发展目标,介绍了多层雷达吸波材料的研究现状和几种宽频吸波结构的设计方法.分析讨论了采用多层结构的雷达吸波材料,以及依据阻抗匹配原理提高材料吸波性能的可能性.提出将多层吸波材料和宽频吸波结构结合得到一种涂层型的薄型(20μm左右)多层雷达吸波材料的研究思路,建立了薄型多层雷达吸波材料由多层结构、表面为离散式分布的斑点、内部再穿插一些非吸波薄膜的材料模型.初步试验表明这种薄型多层雷达吸波材料可以提高吸波性能.

| Abstract: | According to the development direction-thin thickness,light density,broad frequency band and intensive results of RAM, recent studies of multilayer RAM and designing methods of several broadband absorbing structures were discussed. RAM with muhilayer structure and possibility to improve absorbing ability according as impedance matching principle were analyzed. Thin muhilayer radar absorbing material integrating the multilayer RAM and the broadband structures is studied to enhance absorbing properties of RAM, and the novel structure of the thin multilayer RAM will produce a new field in the study of RAM. This muhilayer structure is made of disperse spot on the surface, non-absorbing film inserted into inner. It indicates that the structure can improve absorbing ability according to primary experiments. |
