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.
