摘要
根据混沌运动中键波频带宽度的一种估算方法设计了一个基于Chua电路的键波同步系统,通过仿真实验给出了影响混沌同步的主要因素和键波频带宽度估算的正确性,并研究了混沌键波同步系统在弱信号检测中的应用及检测信号频谱对基于混沌同步弱信号检测性能的影响,为混沌键波同步系统在弱信号检测中的实际应用奠定了一定的基础.
According to the method for estimation bond frequency band in the chaotic motion, a bond wave synchronization system based on Chua circuit is designed, the major factors of influencing chaotic synchronization is presented by experiments, at the same time, the correction of this estimation method is also demonstrated; and then, the application of Chaos synchronization system in weak signal delectation and the influence of detecting signal spectrum to weak signal detection performance based on chaotic synchronization by experiments are analyzed, the research in the paper provides the foundation of putting chaotic bond wave synchronization into practice application to weak signal detection.
