摘要
提出了一种在极不稳定的混沌系统中进行信号测量的方法,将敏感元件作为混沌电路的一部分,在初值一定的条件下,利用混沌系统的参数敏感性,敏感元件的参数随待测信号变化并使系统的混沌轨道变化,定义了轨道距离。从理论上和特定电路实验上论证了混沌测量方法是可行的。
The idea of measuring weak signal in unstably chaotic system is described. Fixing initial conditions, chaotic orbits change with parameter of sensor in nonlinear circuit. A distance between two orbits has been defined. By measuring distance of chaotic orbits, very weak signal can be detected because of the sensitive dependence on parameter. This measurement method is confirmed in this paper by chaos theory and circuit experiment.
