摘　　要：为了揭示扫频式干扰对调频多普勒引信的干扰机理,在分析谐波定距调频多普勒引信的工作原理和扫频式干扰信号特征的基础上,理论推导了扫频式干扰信号作用下调频多普勒引信的响应过程,阐明了扫频式干扰对调频多普勒引信的干扰机理,并进行了仿真分析和试验验证。理论推导、仿真分析和试验表明:与点频干扰相比,扫频式干扰本身具有容错性,通过合理设置扫频参数,即可对谐波定距调频多普勒引信进行干扰,但引信加入各谐波间的严格逻辑时序判决措施后,其干扰效果会变差。In order to reveal the jamming mechanism of frequency sweep jamming to FM Doppler fuze,the response of FM Doppler fuze under the condition of frequency sweep jamming is deduced based on the analysis of the operational principle of FM Doppler fuze and the frequency sweep jamming signal feature.The jamming mechanism of frequency sweep jamming to FM Doppler fuze is elucidated,and the simulation analysis and experimental verification are carried out. Theoretical derivation,simulation analysis and experiment indicate that,compared with single-frequency jamming,frequency sweep jamming is fault-tolerant,and can successfully jam the FM Doppler fuze by reasonably setting the sweeping parameters; but its jamming effect will get worse when the FM Doppler fuze employs the strict logic timing judgment between different harmonics.
