目前使用的常规d MO数据处理方法忽略了速度的影响,认为D MO处理对速度不像全偏移那样敏感。
Ordinary DMO processing methods neglect the influence of velocity because some people think that DMO processing is less sensitive to velocity than full migration processing.
其中阶梯型全倾角偏移既能有效地消除交叉干扰,又能保持大倾角反射波的振幅特性。
The all-dip migration using ladder difference scheme not only effectively removes cross-interference but also preserves amplitude characteristic of steep-dip reflections.
算法结合误差曲面特性以及运动矢量中心偏移特性,得到最佳参考运动矢量;利用运动矢量的方向和强度信息,确定搜索方向,切换搜索模式,搜索的同时应用全零块的中止准则。
It gets the best reference motion vectors from the error - surface and the center deviation characteristics, and it USES the direction and intensity information to choose the proper searching mode.
