Based on the Duffing equation, a Duffing oscillator algorithm (DOA) to improve the signal-to-noise ratio (SNR) was presented. By simulated and experimental data sets, it was proven that the signal-to-noise ratio (SNR) of the weak signal could be gr

这篇文章对微弱信号的混沌检测有一定的研究，对混沌相图判别有无微弱信号。-This article on the detection of weak signals in a certain chaos research, determine whether the phase diagram of chaos weak signal.

混沌源代码，微弱信号检测中很有用的，欢迎下载-Chaotic weak signal detection in the source code, very useful, welcome to download
