By analyzing principle and method of wavelet denoising and the Duffing oscillator , this paper presents a joint detection measurement system that was composed by wavelet denoising and the Duffing oscillator. Simulation experiment shows that using joint measurement system to detect weak signal from high noise background have a more satisfactory result, and further improve the ability of detecting weak signal. The result in this paper will make a good foundation for developing strong background noise weak signal detection instrument.
