| 摘 要： | 扫频式干扰是调频体制引信的主要威胁之一，但其干扰效果具有一定随机性。为了提高其干扰效率，在理论分析扫频式干扰作用下调频引信失效机理的基础上，提出了一种针对单通道调频多普勒引信的窄带扫频式干扰优化方法，可以获取最优的扫频频率步进点数，并依此进行非等间隔频率步进的窄带扫频式干扰。仿真与实测结果表明，该方法可以提高扫频式干扰的干扰效率，同时该方法也可以为成功干扰采用多通道等抗干扰措施的调频引信提供理论设计依据。

| Abstract: | Frequency sweep jamming is one of the main threats to the current frequency-modulated continuous-wave (FMCW) radio fuze while its jamming probability has certain randomness. To improve the jamming performance, an optimized narrow-band sweep jamming approach for single-channel FMCW Doppler radio fuze is proposed based on the analysis of the corresponding failure mechanism of the FMCW fuze. This approach is an unequal-interval frequency sweep jamming with optimized stepped-frequency points. The simulation and measurement results show that this approach enhances the effect of sweep jamming, and it also provides a reference to the design of jamming scheme for the FMCW fuze with multiple-channels or some other anti-jamming measures. |
