The method of residual normal moveout 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。
Then, the signal amplitudes and noise covariance matrices are estimated by using an algorithm in CMP gather after static and normal moveout.
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；
Floating datum method is divide the static of relative fixed datum into two parts that are applied to seismic data before and after NMO respectively and the division is done on CMP gather.
浮动基准面方法是将相对固定基准面的一份静校正量分解成两部分，并分别在动校正前、后应用的一种处理手段，这种分解是以CMP道集为单位的。
