Anisotropic velocity models
- The recorded wave field
is computed in
3-D velocity models
composed of
two homogeneous layers
separated by one curved interface that is either non-inclined or
inclined. The anisotropy in the upper layer is triclinic
and represents dry Vosges sandstone (Mensch & Rasolofosaon, 1997).
The bottom layer is isotropic.
- The migration is performed
using single-layer homogeneous models. The reference migration
velocity consists of the triclinic (TA) layer. In addition,
the following single-layer models with
different anisotropy symmetry
are used.
