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.
