摘　　要：跳频通信系统的关键技术是跳频序列的同步。利用混沌序列作跳频码,取代了跳频通信中常见的伪随机序列。为了解决混沌跳频序列的同步难题,提出了一个以动态双频构建跳频序列同步的新方案。利用M atlab下S im u link仿真平台,对动态双频同步方案进行建模与仿真,结果表明该同步方案用于跳频通信可获得满意的通信效果。The key technique is synchronization of frequency-hopping（FH） sequence in frequency-hopping communication system.This paper proposes to use chaotic sequence as FH codes,substituting the common pseudo-noise sequence in FH communication.In order to solve the difficulty in synchronization of chaotic FH sequence,the author proposes a new method using dynamic double frequency to realize the synchronization of chaotic sequence.In this paper,based on the Matlab/Simulink platform,modeling and simulation are implemented,which show that the synchronous method acquires the satisfying communication effect in FH communication.
