Yang Bao-jun · Dianzi xuebao · 2004
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.
