The Principle of Detecting Faint Characteristic Signal Based onChaotic Oscillator and its Application

介绍了利用混沌振子检测微弱特征信号的原理和实现方法．实验表明该方法能够在信噪比相当低的情况下检测出微弱的特征信号。

The principle and method of detecting faint characteristic signal based on chaotic oscillator is introduced in this paper. The simulation experiment results show that this method can detect the faint characteristic signal from input signal thought the input signal is very low signal to noise ratio(SNR). The application of the vibration signal measured from rolling bearing indicates that this method is effective.
