The method of residual normal moveout analysis for multiple is based no NMO correction of CMPgather.
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 CMPgather 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;
3
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 CMPgather.
