摘要:无人机作战飞机(UCAV)快速发展的同时,无人机平台天线的频率选择表面(FSS)技术也得到广泛应用。设计和测试了一种用于无人作战飞机天线隐身的多层频率选择表面,多层频率选择表面通带为K频段,并且有一个很宽的阻带。数值结果和测试结果验证了该频率选择表面的有效性。该设计
技术可以广泛应用在今后无人作战飞机天线隐身上,也可以用在其他隐身平台的相关天线设计中。关键词:无人作战飞机:天线隐身设计:频率选择表面:雷达散射截面缩减

Abstract : With the rapid development of unmanned combat aerial vehicle( UCAV) ,the frequency selective surface(FSS)technique has been widely applied for the antennas of unmanned combat aircraft vehicle. This paper describes the design and measurement of a multi-layer FsS in order to reduce the radar cross section(RCS) of the antennas of UCAV. The proposed FSS has the pass-band centered at K band and al-so wide out-of-band rejection. Numerical results and measured results show the efficiency of the proposed FSS. The technique proposed in this paper can be widely applied in UCAV' s antenna stealth and other stealth platforms' antenna design.
Key words : unmanned combat aerial vehicle( UCAV) ; antenna stealth design;frequency selective surface ; radar cross section reduction

无人作战飞机(UnmannedCombatAerialVehi-cle,UCAV)由于不需要作战人员直接面临各种威胁,实现零伤亡,而被广泛用于空中作战,在军事上和政治上都有很强烈的使用需求。伴随着战场的信息化发展,自前无人作战飞机主要用于空二空/空地攻击、侦察监视、通信中继等。无人作战飞机快速发展,其面临的威胁也愈加严重,特别是在拒止空间,面临多种有源及无源的探测,多频段高功率干

扰、拦截等。为了适应多变、恶劣的战场环境,提高 UCAV的生存能力和作战能力,除了提高机载的传感器、飞行系统、武器系统的能力外,UCAV的隐身性能越来越受到关注。世界各国都在不断发展隐身相关技术,提高飞机的隐身水平[1-2」,降低UCAV在战场被探测、截获和攻击的概率。无人机目前最主要的隐身技术包括雷达隐身、辐射隐身和红外隐身其中,雷达隐身的核心是降低无人机平台的雷达散射截面积(RadarCrossSection,RCS)[1,3],防止被敌
