摘　　要：接收机中钟差数据的建模具有重要的实用意义。因此,针对所得到的接收机钟差数据,对接收机钟差模型进行了研究。目前,所建立的常用钟差模型有二项式模型、卡尔曼模型和灰色模型。在这三种钟差模型的基础上,提出使用滑动窗以及时排除老旧数据的影响。通过利用三种钟差模型对所得接收机钟差数据进行建模,对加滑动窗后的预测精度进行仿真分析。结果表明,使用滑动窗后的钟差模型能在剔除老旧数据的基础上达到对预测精度的要求。The modeling of receiver clock bias is of siginificant practical applications value,and with the obtained receiver clock bias data, the receiver clock bias model is studied. At present, the binomial model, kalman model and grey model are widely used,this to prevent the bad influence of the old receiver clock bias data. And sliding window is adopted on the basis of these three models. The obtained data by receiver is uesd to set up and simulate these three clock biasmodels, and the analysis result indicates that the prediction accuracy could be up to standard when the sliding window is added.
