摘　　要：为了提高鱼雷主动电磁引信的抗干扰能力,把跳频技术应用于鱼雷主动电磁引信中,提出了基于高速数字信号处理和直接数字频率合成的跳频引信系统设计方案,阐述了跳频引信的工作原理,重点研究了跳频信号的产生及回波信号的处理,并对跳频引信的抗干扰性能进行了理论和仿真分析。仿真结果表明,宽频带跳频工作体制有利于提高鱼雷主动电磁引信的抗干扰能力,可为鱼雷主动电磁引信设计提供新的技术途径。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.
