摘要
提出一种基于混沌理论的纳伏级正弦信号的测量方案,给出了对正弦信号进行混沌检测的原理与方法,仿真实验表明将该混沌检测系统与本文所设计的纳伏级正弦信号发生器相结合,在任何零均值色噪声背景下对微弱正弦信号的检测下限可降至nV级的水平。
We present a detection scheme of nV-level sine signal, which based on the chaotic theory, prove the principle and method of the chaotic detection to a sine signal, simulation experiments show that the detection low limit decreases to nV-level of a weak sine signal under the background of the free zero-mean value color nois while the chaotic detection system combines with the generator of nV-level sine signal ,which is preposed by this paper.
