混沌振子实现微弱周期小信号的检测

Chaotic Oscillators Achieve Faint Periodic Small Signal Detection

通过对混沌振子Duffing方程及其检测原理的介绍,发现混沌振子对周期小信号具有敏感特性,能够在强噪声环境下实现对微弱周期小信号的检测。Matlab实验仿真和分析证明了采用混沌振子Duffing检测微弱周期小信号的可行性。

It is a find that chaotic oscillators is sensitive to faint periodic small signal by introduction about chaotic Duffing equation and detection of theory, and it can detect the faint periodic small signal in strong noise background. It was indicted that the detection is feasible, make use of chaotic Duffing equation by Matlab simulation result and analysis.
