CHESS电台采用差分跳频技术，实现了短波频段内高跳速和高数据传输速率，对通信对抗提出了新挑战。分析了差分跳频序列生成原理，基于CHESS电台结构，构建了差分跳频通信系统抗干扰性能仿真模型，对高斯白噪声信道和瑞利衰落信道下差分跳频信号的抗干扰能力进行了仿真分析。结果表明，部分频带干扰对差分跳频具有较强的干扰能力。在此基础上，提出了CHESS电台的干扰策略，可为我军的电子对抗提供参考。

The CHESS radio which make use of differential frequency hopping technology may help us achieve high hopping rate and high velocity of data transfer in short wave, this also puts forward a new challenges to communication countermeasure. In this paper, the basic principle of the DFH sequence form was analyzed. Based on the framework of CHESS radio, the simulation model for DFH system is designed. The ability of DFH and general HF against jamming over the AWGN channel as well as Rayleigh fading channel were simulated. The results show that partial-band jamming has strong performance against DFH. At last, some jamming tactics for CHESS radio are proposed, which can provide reference for the electronic countermeasure of our army.
