基于混沌振子探测微弱动态周期测量信号

The Weak Dynamic Periodic Measurement Signal Detection Based on Chaotic Oscillators

介绍了Duffing振子检测微弱信号的原理和过程以及利用混沌振子来检测淹没在强噪声背景中的微弱动态周期测量信号的方法.理论分析和仿真实验均表明混沌振子能有效地检测微弱动态周期信号.该检测方法既能形成一种独立的检测理论,也可以作为现行微弱信号检测理论的有效补充.

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.
