资料介绍

从理论上分析了二维Duffing弱信号检测系统变量输出在混沌和周期态之间交替转换。发现一种新的三维混沌弱信号检测系统生成规则,以生成4种检测系统之一的三维Liu-cos混沌系统为例,采用傅里叶变换等方法从理论上验证了新生成的三维混沌弱信号检测系统输出信号具有广域收敛性,解决了二维Duffing混沌弱信号检测系统不能广域检测和输出信号不收敛问题;新设计的三维Liu-cos混沌弱信号检测电路空中声波实验显示可抗低频声波干扰,检测性能优于二维Duffing混沌电路和新设计的Duffing+滤波器电路,水中实验显示三维Liu-cos混沌弱信号检测电路可抗高频水声干扰,可检测波形畸变的水声信号。

The output wave changes between periodic and chaotic state of the variable in the two dimensional Duffing chaotic weak signal detection system were analysed. A new rule to generate the three dimensional chaotic weak signal detection system was discoveried. Making the three-dimensional Liu-cos chaotic weak signal detection system generated by above the rule as one of the four detection systems for an example,the wide convergence of the output signals of the threedimensional chaotic weak signal detection system generated by the rule was verified by using the Fourier transform theoretical. The problems for the signal can not be detection in the wide area and can not be convergence by the two dimensional Duffing chaotic weak signal detection system were solved. The experiments in air showed that the low-frequency acoustic interference can be overcome by the new designed three-dimensional Liu-cos chaotic weak signal detection circuit.The detection performances of desigened three-dimensional Liu-cos chaotic weak signal detection circuit are better than the two dimensional Duffing circuit as well as the new designed Duffing and Filter circuits. The experiments in water showed that the high frequency acoustic interference can be overcome and the distorted acoustic signal can be detected by the threedimensional Liu-cos chaotic weak signal detection circuit.
