WebWe acquired both SH - and P -wave data in common‐offset gathers with a near offset and a far offset and found that although the SH -wave data show clear azimuthal variations in AVO, the P -wave signals show no apparent changes with azimuth. We then applied numerical modeling to analyze the data. Definition Scattering of seismic waves is best defined by reference to a laterally homogeneous or slowly varying medium where the wave fronts can be perfectly tracked and the propagation of waves can be successfully described by geometrical methods such as ray theory. See more To introduce the various scale lengths that enter in the modeling of seismic scattering, it is convenient to consider a thought-experiment such as the one shown in … See more Following the statistical approach, it is natural to characterize the propagation in the random medium by calculating the moments of the wavefield u.
