摘要
降低雷达天线的RCS而又保证雷达自身正常工作已成为目标隐身技术中的一个关键课题。介绍了由十字型振子单元构成的带阻式频率选择表面(FSS)的选频特性,探讨了FSS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2点结论,并指出在副反射面天线的工程应用中更容易实现。
It is a key problem of objective concealment technology to reduce radar antenna RCS and guarantee radar itself work regularly. The frequency select characteristics of band stop FSS （frequency select surface） composed of cruciform vibrator units is introduced. It is discussed FSS engineering application in low RCS parabolic reflector antenna and low RCS Cassegrain antenna, which is composed with crisscross element units. The concealment function is analyzed when the FSS is applied to the primary and secondary reflex antennas. Finally, two conclusions point out that the secondary reflex antennas are easy to realize in engineering application.
