摘　　要：为应对新体制无线电引信带来的威胁,从引信对抗角度以超宽带无线电引信为研究对象,研究干扰作用下其失效机理。揭示了超宽带无线电引信敏感干扰波形响应机理,理论推导了周期调制干扰信号作用下引信响应特性,仿真计算了在射频噪声、正弦波调幅、正弦波调频以及扫频正弦波调幅干扰信号作用下超宽带引信接收机相关器输出响应特性。以干信比增益为表征参量,通过理论计算、仿真及试验验证得出结论:周期类调制干扰中调幅类干扰对超宽带引信干扰效果最好。To deal with the threaten of new type radio fuze,we focus research on the interference mechanism of ultra wideband(UWB)radio fuze which is a new type radio fuze.In this paper,the response mechanism of the UWB fuze sensitive waveform is revealed,the response characteristic of fuze under periodic modulation jamming signal is deduced theoretically,and the correlator response characteristic of fuze under the interference of noise,sinusoidal amplitude modulation,and sinusoidal frequency modulation signal,is calculated and simulated.Based on the signalinterference-ratio gain,through theoretical calculation,simulation analysis and experimental verification,it is concluded that the AM sweep jamming is the more effective than the FM sweep jamming in the periodic modulation interference.
