摘要
采用选择性透波天线罩技术可以在天线正常工作的前提下,改变天线舱在天线工作频段外的RCS特性,因此可以实现天线舱的带外隐身。本文对频率选择表面的工作原理和应用领域进行了概括,对比了选择性透波天线罩和普通天线罩透波原理的区别,归纳了选择性透波天线罩的设计、分析方法和典型的加工方法,以及选择性透波天线罩技术的技术难点,同时,对选择性透波天线罩技术在有人机和无人机上的应用进行了简要的分析和探讨。
Provided that the antenna is working normally, the selective wave transmission antenna radome technology may change RCS characteristics of the antenna compartment when it is out of the antenna＇s operating frequency range, thus it is a realization of out-of-band stealth of antenna compartment. This paper summarizes operation principle and application field of frequency selective surface, makes a comparison of wave transmission principles between the selective wave transmission antenna radome and common antenna radome, concludes design, analyzing and typical processing methods of the selective wave transmission antenna radome, as well as, its technical difficuhies. Finally, it briefly analyzes and discusses the application of the selective wave transmission antenna radome technology on manned and unmanned aircraft.
