摘要
利用混沌系统的相轨迹对初值敏感而对噪声免疫的特性,提出采用三角波和正弦波分别作策动力对微弱三角波信号的幅值进行检测。最后,在Matlab/Simulink环境下进行仿真实验。结论表明:混沌理论可以实现对信噪比很低的三角波信号幅值进行检测,并且取得较高的精度。
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.
