摘　　要：目前常用的混沌振子检测微弱光电信号幅值的方法还是局限在传统的Duffing方程上,但由于其结构简单,其动态特性具有一定的局限性。在详细研究典型混沌振子动态特性的基础上,将复杂的Lorenz混沌方程和Rsslor混沌方程应用到强噪声背景下微弱光电信号幅值检测中,旨在探索检测微弱光电信号幅值的新方法,仿真结果验证了该检测方法的有效性。Nowadays the traditional method of detecting weak signal amplitude is Duffing Equation. It is limited in engineering application because its structure is very simple and its dynamic characteristics are complex. In this paper the typical chaotic oscillators are studied and the Lorenz Equation and Rossler Equation are used in detection weak photo-electric signal amplitude which is submerged in strong noise. Its purpose is to find new detection method of weak photo-electric signal. The simulation results verified that it is effective.
