摘　　要：文章分析了基于混沌检测弱信号的原理,针对目前利用混沌检测弱信号中存在的两个关键问题,构造出一种利用基于Chua电路混沌同步检测弱信号的系统,利用此系统解决了混沌检测弱信号中存在的问题,实验证明了此方案的可行性,为混沌同步在弱信号检测的实际应用奠定了基础。In this paper, the basic principle of weak signal detection based on chaos is analyzed. Aiming at some key problems existing in weak signal detection based on chaos, a new system is constructed, which detects weak signal utilizing chaotic synchronization characteristics based on chua cireuit. Utilizing the system, the critical problems of existing in weak signal detection based on chaos can be solved. Experiments validates the project, and as a result, the research in the paper provides the foundation for putting chaotic synchronization into practice application of weak signal detection.
