    Abstract
  • To improve the anti-jamming performance of torpedo active electromagnetic fuze, the frequency hopping technology is applied to the design of torpedo active electromagnetic fuze. Accordingly, a frequency hopping fuze sys-tem based on the high-speed digital signal processing and direct digital frequency synthesizer(DDFS) is proposed. The principle of the fuze system is elaborated with focus on the generation of the frequency hopping signal and the process-ing of the echo signal. And the anti-jamming performance of frequency hopping fuze is analyzed in theory and simula-tion. Simulation results show that the broadband frequency hopping working system can improve the anti-jamming per-formance of torpedo active electromagnetic fuze.
