摘　　要：建立了光孤子测量光纤应变的一个简单模型,研究如何利用卡曼滤波器对这个模型的测量数据进行处理,指出卡曼滤波在这种情况下是时间不变的。尽管光孤子到达时间的抖动正比于它的运行时间,但经过较长时间的测量,测量结果的方差可以保持为一常数,说明这个方案是可行的。The simple model about the measure of the fiber strain with optical soliton is analvsed and how to deal with the data measured by Kalman filter is investigated. The result shows that the Kahnan filtering is time-independent. Though the optical soliton time jitter is in direct proportion to the running time. but through the long time sampling, the variance of the measure result is a constant, which shows the project is feasible.
