摘　　要：在飞行器隐身技术的研究中发现,机(弹)载雷达天线将在飞行器鼻锥方向产生很强的RCS贡献,如何降低雷达天线的RCS而又保证自身雷达正常工作已成为目标隐身技术中的一个关键课题.文中介绍了由十字型振子单元构成的带阻式频率选择表面的选频特性,探讨了该表面在低RCS抛物面天线和低RCS卡塞格伦天线中的工程应用,分析了应用于主、副反射面天线的隐身性能,最后得出两点结论,指出在副反射面天线的工程应用中更容易实现。It is found in studying flying instrument concealment technology that the airborne（missile- launched） radar antenna engenders strong RCS contribution towards flying instrument＇s nose. It is a key problem of objective concealment technology how to reduce radar antenna RCS and guarantee radar itself to work regularly. In this paper, the frequency selecting characteristics of band-stop frequency select surface is introduced simply. The paper discusses the engineering application in of this surface low RCS parabolic reflector antenna and low RCS Cassegrain antenna, which is composed of crisscross element units. The article analyzed the concealment function when the frequency select surface is applied to the primary and secondary reflex antennas. Finally, two conclusions are drawn that the secondary reflex antennas is easy to realize in engineering application.
