| 摘 要： | 混沌理论用于微弱信号检测领域近年来得到较快发展.实验室内研究,需要产生包括混沌噪声在内的各种噪声,并叠加微弱周期信号作为微弱信号检测系统的信号源.文中介绍基于Lab-VIEW平台并结合Matlab计算模块的混沌噪声发生器,可产生典型的3种混沌噪声:Logistic、Duffing、Lorenz形式.该发生器将LabVIEW易于接口实现和Matlab计算精度高、编程简捷的特点相结合,并通过USB-6008模块外扩高速DAC芯片AD5405实现单通道信号噪声输出;具有结构清晰、通用性强、易于实现、使用方便的特点.

| Abstract: | Chaos theory that was used in weak Signal detection area is developing very fast. In laboratory research, all kinds of noises, including chaotic noise should be generated and iterated with weak periodic signal as source for weak signal detection system. A chaotic noise generator, which can generate three typical chaotic noises, such as Logistic, Duffing and Lorenz, was realized based on LabVIEW and computation module of Matlab. Combined with the convenience of LabVIEW's interfacing with external devices and the high calculating precision of Matlab programming, it can output one-channel signal and noise with USB-6008 model extending DA5405 externally; it shares many characteristics, such as clear system structure, strong currency, easy to be realized and convenience to be used. |
