摘　　要：在超低空攻击巡航导弹的场景中,由于脉冲多普勒引信存在距离模糊,可能会出现虚警的现象。本文对脉冲多普勒引信的模糊图及海面回波特性进行分析,提出了随机脉位调制、随机二相码调制和重复频率跳变三种距离副瓣解决措施,并进行了对比分析。结果表明重复频率跳变具有良好的抗距离副瓣性能。When attacking cruise missile at ultra-low altitude,the pulse Doppler fuze may appear false alarm at the range sidelobe due to range ambiguity.In this paper,the ambiguity graph and the sea echo characteristics of the pulse Doppler fuze are analyzed,then three solutions of range sidelobe false alarm are proposed and compared,which are random pulsed phase modulation,random binary-phase modulation and repetitive frequency hopping.The results show that the repetitive frequency hopping method has good performance of anti range sidelobe.
