| 摘 要： | 目标物体上表面波的衰减吸收对目标的隐身起到很大的作用.研究了雷达吸波涂层对宽频段雷达表面波衰减吸收的规律以及频率选择表面与吸波涂层相结合的复合吸波涂层对宽频段表面波衰减吸收的规律.实验结果表明,低厚度的雷达吸波涂层就可以实现高频表面波的强衰减吸收,而频率选择表面与低厚度雷达吸波涂层相结合的复合涂层与雷达吸波涂层共同交替使用可以实现宽频段表面波的强衰减吸收,有望实现目标物体在宽频段范围内的高性能均衡雷达隐身.

| Abstract: | Attenuating and absorbing of surface wave on targets is vital for targets' stealth. Characteristics of attenuating and absorbing of super wideband radar surface wave by means of radar absorbing coatings as well as radar absorbing coatings combined with frequency selective surfaces are studied and then reported here. The results show that thinner radar absorbing coatings can strongly attenuate high frequency surface waves ,while alternate using of thin radar absorbing coatings and thin radar absorbing coatings compounded by frequency selective surfaces can strongly attenuate wideband surface wave and it is possible that high performance balanced stealth of super wideband can be reached using the alternate radar absorbing coatings. |
