Using step surface data for wave equation simulation of seismic data can produce serious interference at corner points of steps and further affect the results of numeric simulation.
The surfacewave is treated as interference wave in oil seismic prospecting, however, the Rayleigh wave, like the refraction and reflection waves, contains the information of underground medium.
The feasibility and effective of the multi-radial mid-value filtering have been verified through some model data tests and suppressing the surfacewave in the practical pre-stack seismic data.
