原子钟时间尺度与Kalman滤波器

Application of Kalman Filter in Atomic Time Scale

Kalman滤波器是随机信号处理中一种常用的滤波算法,多用于信号的估值及预测,近年来也出现于原子时算法中。本文介绍了国外在这一研究中一些最新发展及作者自己的一些研究成果。讨论了Kalman滤波器的基本原理,Kalman滤波器用于时间尺度的不同方法以及存在的问题,特别讨论了Kalman滤波器的稳定性问题。

Kalman Filter seems to provide a logical system, which can take into account allof the measurements within an ensemble of clocks. In recent years many papers onthis topic appeared. But it is still a fresh subject in China. The Kalman Filter andthe principle of Kalman Time Scale are introduced breifly and particularly thestability of the Kalman Filter is discussed in this paper
