摘　　要：通常频率选择表面雷达罩借助其几何外形,将带外信号反射到远离来波的方向,从而实现隐身.然而随着多基雷达反隐身技术的发展,这种反射信号仍然可以被侦测到.针对这一难题,提出一种加载电阻膜吸波材料的新型频率选择表面.该频率选择表面在低频工作带通内,不仅对大入射角和不同极化电磁波具有稳定的带通特性,而且在高频带外对电磁波表现出吸收特性,可以将探测信号吸收掉,从而大大降低被反隐身多基雷达探测的风险.另外,由于吸波材料的作用,使得频率选择表面的栅瓣也得到了很好的压制,降低了栅瓣对频率选择表面工作频带的干扰.Commonly, by virtue of the frequency selective surface （FSS） radome＇s shape, out-band signals are reflected to other directions to achieve a stealth radome. However, with the development of the anti-stealth of poly-state radar technology, such reflected signals can be still detected. In view of this problem, a novel frequency selective surface loaded with resistance film absorbers is proposed. Such an FSS not only has a stable performance for various incident angles and for different polarizations, but also possesses absorptive property to electromagnetic waves in out-band. By virtue of this advantage, the out-band signals can be absorbed and the risk of anti-stealth detection can be greattly reduced. In addition, because of the function of the absorber, grating lobes of the FSS are also restrained, which reduces the interference of operating band.
