Introduction
- We approximate the "recorded wave field" by ray-theory synthetic
seismograms.
- We apply ray-based Kirchhoff prestack depth
migration to calculation of migrated sections in 2-D and 3-D simple
anisotropic velocity models.
- We test Kirchhoff prestack depth migration in two ways:
a) the anisotropy used for computation of the recorded wave
field is the same as the anisotropy
used for migration,
b) the anisotropy used for computation of
the recorded wave field differs from
the anisotropy used for migration.
