摘要
基于混沌理论构建的信号检测系统具有敏感微弱周期信号和对噪声有强免疫力的特点,用于微弱信号检测领域优势明显。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。介绍一种基于LabVIEW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,Duff-ing,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,具有结构清晰、通用性强、易于实现、使用方便的特点。
Signal detection system based on chaos theory has the critical sensitivity to periodic signal and the immunity to the strong noise, which can be used in weak signal detection area. In laboratory study, all kinds of noise including chaotic noise, are needed to be generated, which iterated with weak periodic signal is used to be signal source. A kind of chaos signal generator based on LabVIEW platform and Matlab calculation module is presented, which can generate three common chaos noise signal： Logistic, Lorenz, Dulling. This generator combing the convenience of LabVIEWts interfacing with external devices and the high calculating precision and the concision of Matlab programming, has clear system structure,strong currency,easy to be realized and convenience to be used.
