Johnson Noise Thermometry Research Based on Cross Correlation Analysis;
基于互相关分析的约翰逊噪声测温法研究
With the classical Johnson noise, 1/f noise and radiation noise, the dependence of noise and Signal-to-Noise on different parameters were simulated.
针对微测辐射热计中的约翰逊噪声、1/f噪声与辐射噪声,着重探讨了微测辐射热计的偏置电压、电阻、噪声带宽等参数对其噪声和信噪比的影响,并根据分析仿真结果,提出了三种增加微测辐射热计信噪比的方法。
Base on the attribute about Johnson Noise is that the basic principle representation of heat locomotion of electronics,construct that accurate temperature measurement system dispense with cyclicity demarcate.
基于约翰逊噪声是电子热运动即器件电阻的本质表现法的属性,构建了不要求周期性定标的精确温度测量系统,分析了实现精确测温所遇到的理论性问题并提出了具体解决方案,同时考虑了测温法中涉及到的两个信号处理的概念,采用间接互相关分析算法论证了除噪效果的应用,给出了系统信号测量及处理的方案。
