The algorithm uses the technology of wave field extrapolation and the wave equation migration by finite difference approach,which can be used in common offset gathers,for 3D material requires common offset gathers with the same azimut.
该算法应用波场外推的技术及波动方程偏移的有限差分算法,可在共偏移道集上实现,对于3D资料须应用同方位角共偏移距道集。
In this paper, the method of wave field extrapolation and decomposition of seismic compound wave in viscoeleastic medium is presented, based on wave equation.
从粘弹性波动方程出发，建立了一种地震散射波场纵横向高分辨波场外推方法。
