摘　　要：为对谐波雷达引信提供天线实现方案,解决收发天线谐波频率跨越较大的问题,设计了一种收发为三次谐波关系的共口径引信天线,在空载武器系统受限的安装空间下,实现了X波段及Ka波段的前端近距探测。同时设计加工了一种嵌入式频率选择表面谐波双频窄带引信天线罩,经计算测试,天线罩实现了谐波频率窄带窗口选择,为谐波雷达体制引信抗强有源干扰提供了一种新的技术形式。The committed character of harmonic radar is that the receiving signal freckly is three times of transmitting signal.Then the band of antenna is very wide.A compact shared-aperture fuze antenna is designed using X-band as the transmitting frequency and Ka-band as the receiving harmonic frequency.A dual-band and frequency selective radome is designed and fabricated.The radome can be considered as a narrow-band filter.The transmitting and receiving antenna share the same radome.This radome is a kind of simple and effective measure which improves the capability of wide band blanket anti-jamming.
