摘　　要：针对混沌信号的确定性、类噪声性、连续宽带频谱等特性 ,本文提出将混沌信号用于通信对抗 ,利用混沌信号代替噪声对敌方实施“混沌干扰”。文中以 L orenz混沌系统为例 ,分析了该混沌信号的特性 ,并讨论了存在干扰下的同步性能 ,应用 Matlab对通信对抗效果进行仿真 ,仿真结果表明基于混沌的通信对抗措施具有较好的效果。Based on ascertainableness, noiselike and broadband frequency spectrum of chaos signal, chaos signal applied in communication countermeasure is proposed in this paper,noise is replaced with chaos signal to jam enemy′s communication equipment Take Lorenz chaos system as an example, analyses the property of Lorenz, and discusses the synchronization ability in the circumstance of noise, simulate the process of communication countermeasure with Matlab, which show the good results can be gained

关 键 词：LORENZ混沌系统 混沌同步 通信对抗 干扰
