Therefore, moveout transform filtering method in T-X domain was adopted, which linearized the curved coherent noise in T-X domain, and remove noise by the contrast of apparent velocity.

为此，采用T-X域时差变换滤波技术，即在T-X域内将曲线型相干噪声线性化，通过视速度差异去除噪声，从而达到压噪目的。

Then the trace gather undergoes velocity analysis, normal moveout correction and stack to bring seismic migrated section ( This is called scattering point imaging).

然后对该道集进行速度分析、动校正和叠加，得到偏移地震剖面，即共散射点成像。
