摘要
本文给出了一种典型的间歇混沌模型—— Duffing混沌振子 ,并详细的分析了其间歇混沌特性 .基于混沌现象发生随模型参数变化的间歇性 ,设计了噪声背景下弱信号的检测方案 .
A typical intermittent chaotic model--the Duffing oscillator, is researched and its character of intermittent chaos is also studied in detail. It is designed that the method of fake signal detection under strong noise, which based on the intermittence of chaos with model parameters′ change. The result of emulation is presented in the end.
