　　In order to improve the accuracy of slow deformation monitoring sequence,the smoothing filter is usually used.On the basis of weighted moving average method,a robust moving average method is proposed.An adaptive windowing method is developed and combined with ARMA time series analysis to improve the prediction precision of monitoring sequence.
