| Abstract: | A new chaos detection model without driving force is presented based on the analysis of Duffing oscillator＇s dynamic characteristics.Combined with the self-correlation detection technology,the amplitude of sinusoidal signal with known frequency and unknown phase can be detected.Simulation experiments show that the method is effective. |
