频率选择表面天线罩研究现状与发展趋势

Status and development of frequency selective surface radome

由于雷达天线系统自身工作的特点,他必须保证自身雷达波的正常接收和发射,常用的隐身措施无法简单地在雷达天线隐身中获得应用.采用频率选择表面(FSS)技术与天线罩技术相结合形成FSS天线罩,可以使天线罩获得频率选择的功能.即FSS天线罩对雷达的工作频段提供带通的传输特性,同时改变雷达工作频段以外的雷达散射截面(RCS)特性,可以实现带外隐身.本文分析了FSS天线罩制备的基本思路,综述了国内外FSS天线罩在结构设计、制造工艺等方面的研究状况,并从多频FSS天线罩、智能FSS天线罩、厚屏FSS天线罩、微型化FSS天线罩以及各技术的组合等方面对FSS天线罩的发展进行了展望.

Due to the working characteristics of radar system, i.e. it has to ensure the emission and acceptance of its own radar wave, frequency selective surface （FSS） radome is the most effective stealthy way to give radome the function of frequency-selective. Com-bining the FSS technique and the radome together, FSS radome provides bandpass transmission properties in the operating frequency of radar, and changes the RCS characteristics of the antenna compartment when it is beyond the antenna’s operating frequency range, thus it is a realization of out-of-band stealth. This paper introduces the basic design of FSS radome technology and summarizes the research status of FSS radome in the structure design and the technology. The muti-band FSS radome, intelligent FSS radome, thick-screen FSS radome, miniaturized element FSS radome and the technologies to construct radome are predicted to be the perspective of FSS radome.
