摘　　要：突破了传统跳频通信必需提前共享密钥的限制,非协调性跳频通信UFH(uncoordinated frequency hopping)无需提前共享密钥,就可以在充满干扰的通信环境中,安全有效地进行数据传输,是一种重要的新型抗干扰通信技术。首先详细阐述了UFH的基本原理以及具体过程,并对其安全性能进行了分析;然后针对基本UFH方案较低的通信效率,分析了五种基于验证方法的改进方案;接着简单介绍了两种基于UFH的初步应用;最后结合UFH的特点,对其以后的发展趋势进行了展望和总结。Breaking through the limitation of traditional frequency hopping communication for a necessary pre-shared key, UFH （uncoordinated frequency hopping） communication becomes an important new antijamming communication technology. This technology could enable the communication parties to safely and effectively transmit data without a pre-shared key in the full-of-interference environment. Firstly, the basic principle and specific process of UFH is described, and its security performance analyzed. And aiming at the fairly low communication efficiency of the basic UFH program, five improved schemes based on verification method are analyzed. Then, two tentative UFH-based applications are briefly discussed. Finally, in combination with UFH characteristics, the future trend of UFH development is forecasted.
