| Abstract: | The principle and process of detecting weak signal by using Duffing oscillator are discussed in detail. Chaotic oscillators are used to detect weak dynamic periodic measurement signal submerged in strong noise background. The theory and simulation experiments show that chaotic oscillators can effectively detect weak dynamic periodic measurement signal. This method can form an independent detect theory and be an effective supplement of existing weak signal detection theory. |
