An algorithm of wave equation datuming



The article describes the wave equation datuming is the procedure in seismic exploration that used for removing of the influence of Weathering Velosity Zone. It means transform the wave field at free boundary to some level below that Zone. Numerical procedure for solving this problem based on reverse time wave continuation. The new thing is that we cut of the ghost waves using characteristics. The results of numerical modeling are represented.
