| 摘 要： | 天线是卫星的强散射源,降低天线的RCS是卫星隐身设计的重要研究课题之一,本文提出了一种基于频率选择表面技术的微小卫星天线罩设计方案,可有效降低卫星天线的RCS。首先针对隐身天线罩设计要求,设计天线罩壁,包括各层介质的介电常数、厚度等。然后设计附着在罩壁上的FSS屏。进一步制作天线罩实物,通过在微波暗室进行天线罩扫频测试,实际测量该天线罩的频率响应特性,并测试星上天线方向图。结果表明,本文提出的天线罩设计可满足微小卫星天线在给定频段的阻带特性,并保持在给定正常工作频段的通带特性,说明该微小卫星隐身天线罩设计是有效的。

| Abstract: | Since antenna is one of the strong scattering sources of a satellite,reducing the antenna RCS plays an important role in the design of the stealth satellite.In this paper,a radome design scheme for radar-stealth minisatellite is proposed by using the frequency selective surface(FSS) technique,to reduce the satellite antenna RCS.According to supposed design requirements for the radome,the design of radome wall is firstly performed,inctuding determining the conductivity and thickness of the medium in each lay... |
