摘　　要：短波差分跳频系统信道带宽宽,频率跳变速度快,能够有效对抗跟踪干扰、阻塞式干扰、多音干扰等传统的干扰方式。文中在分析差分跳频系统的信号传输模型基础上,提出了采用快速多音相关干扰对短波差分跳频系统进行干扰。通过对系统性能进行分析和仿真研究,证明了快速多音相关干扰能够对差分跳频系统实施有效干扰,因而具有很好的应用前景。For its wide frequency band and high hopping speed, DFH system is good for the rejection of traditional trace interference, barrage jamming and multitone jamming. In this paper, based on the analysis of short-wave DFH signal transmitting model, fast multione correlated jamming （FCMTJ） is proposed to interfere DFH system. Comparison of theoretical results and simulation results in dicates that FCMTJ can effectively interfere DFH system, and thus has good prospect.
