摘要

建立一个其动力学行为对微弱方波信号极其敏感的混沌系统

根据该系统相轨迹的变化实现了任意色噪声背景下的微弱方波信号的测量.文中论证了方波信号的检测方法;分析了噪声对混沌检测的影响

仿真实验表明该混沌检测系统对方波信号非常敏感

对任何零均值色噪声均具有极强的抑制能力.

Abstract

We build a chaotic system which dynamic behavior is very sensitive to weak square wave signal

and then use the change of phase space track of this system to realize detection of the weak square wave signal from any colored noise background.In this paper

we proved the square wave signal's detection method and analyzed the influence for the chaotic detection from noise.The simulation experiments shows that chaotic detection system is very sensitive to square wave signal and have strong restrain ability to any colored noise with zero mean.
