摘要以双耦合Duffing混沌振子为研究对象,提出了一种基于双耦合Duffing混沌振子与变尺度相结合的微弱信号检测新方法。分析了双耦合Duffing混沌振子检测微弱周期信号的原理。利用变尺度方法,克服了Duffing振子检测微弱周期信号受频率限制的缺陷。通过双耦合Duffing混沌振子系统与单Duffing混沌振子系统进行比较,表明双耦合Duffing混沌振子系统具有明显的优越性。该方法用于检测任意多频微弱信号具有明显优势。

Abstract：With two coupled Duffing oscillator as the research object, a new method of weak signal detection is proposed based on two coupled Duffing oscillator and variable scale. The detect principle of weak periodic signal based on two coupled Duffing oscillator is analyzed. With the variable scale method,the defect of the Duffing oscillator to detect weak periodic signal by frequency limit is overcomed . Through the comparison of two coupled Duffing oscillator system with single Duffing oscillator system, the advantages of the two coupled Duffing oscillator system are shown. The method used to detect multi-frequency weak signal has obvious advantages.

Key words： metrology multi-frequency weak signal detection two coupled Duffing oscillator variable scale
