提出了基于混沌电路参数敏感性的信号检测方法,并分析了用倒锯齿映射来实现这种参数式检测应用的优点,即实现倒锯齿映射的电路结构比较简单,电路输出的符号序列与映射参数在零初值时能够排序。在以该方法为基础的温度测量实验研究中,加入热敏电阻作为主要的感温元件,使测温精度大大提高,说明该方法具有一定的发展潜力,值得进一步研究。

A signal detection method based on parameters sensitivity of chaotic system is introduced. The advantages of down saw-tooth map in application of parameter measurements are analyzed, that is simple in structure and ordered in zero initial condition. In chaotic circuit experiment of temperature measurement using thermistor as main sensitive element, the accuracy is improved obviously. The results of theoretical analysis and exoeriment show its researching worth.
