| 摘 要： | 首先分析Ｄｕｆｆｉｎｇ方程的基本形式，然后阐述了基于相平面变化进行弱信号检测的工作原理，并给出仿真模型，最后利用此模型进行仿真实验。结果表明，此实验方法具有很低的信噪比工作门限，从而证明了此方法的确是可行的，此方法填补了弱信号检测理论一项空白。

| Abstract: | This paper first analyzes the basic form of Duffing equation,and then describes the principle of weak signal detection based on the change of phase trace.In addition,the simulation model is given.Finally,with this model,a lot of simulation experiments are done.The experiment shows this method has lower SNR,consequently,is proved to be feasible.Thereby,this method fills up a blank to weak signal detection theory. |
