摘　　要：近年来频率选择雷达吸波体(FSR)受到了越来越多的关注,不同于传统的频率选择表面(FSS),FSR能够吸收带外具有威胁性的电磁波,同时无耗透射带内需要的电磁波。因此,采用FSR设计而成的雷达天线罩覆盖在雷达前方并不会影响雷达的正常工作。FSR在军事应用上具有很大的潜力,可以用来减少雷达散射截面(RCS)并提升隐身性能。文章介绍了FSR的国内外研究现状,针对现有FSR类型的部分缺失,提出一类新型的带吸型FSR并给出对应定义,在此基础上研究了一系列具有不同性能面向不同应用的带吸型FSR。Recently frequency selective rasorber(FSR) has attracted growing attention since it can transmit in-band electromagnetic(EM) waves while absorbing out-of-band EM waves. They can be used to reduce bistatic radar cross section(RCS). Therefore, FSR has great potential for military applications to decrease RCS and improve their stealth performance. Firstly, recent research advances of conventional FSRs have been discussed in this paper. Then a novel FSR, called band-absorptive type FSR, has been introduced and its detailed concept has been defined. A series of band-absorptive FSRs with different performance have been presented.
