A method for detecting weak triangle using chaos oscillator

ZHANG Lin,WANG Lian-fen,NING Xiao-lei,CHEN Ming-huan(The Second Artillery Engineering College,Xi'an 710025,China)  
A new method for detecting the amplitude of weak triangle is proposed by choosing triangle wave and sine wave as powers respectively,based on the properties of chaotic system whose phase track is sensitive to the initial value and immune to the noise.The simulation is done in Matlab/Simulink environment at last.The results show that this method can detect weak triangle wave with lower signal-noise-radio at a high precision.
