The method of residual normalmoveout analysis for multiple is based no NMO correction of CMP gather.
多次波的剩余时差分析法是在CMP道集动校正基础上进行的。
2
Then, the signal amplitudes and noise covariance matrices are estimated by using an algorithm in CMP gather after static and normalmoveout.
然后在动静校正后的CMP道集内，采用简捷的算法来估算信号的振幅成分和噪音的协方差矩阵；

The paper analyses the cause of anomalous stretch of normalmoveout in seismic data processing and the characteristics digital normalmoveout correction.
