Anisotropic velocity models with a velocity gradient
- The recorded wave field
is computed in velocity models
composed of two layers with
the triclinic anisotropy representing dry Vosges sandstone
(Mensch & Rasolofosaon, 1997) and
velocity gradients in the upper layer.
The bottom layer is isotropic and homogeneous.
-
The migration is performed
using single-layer heterogeneous velocity models with media
TA-VG and TA-HG and the following homogeneous velocity models
with the TA, VTI-1 and HTI-2 media,
used by Bucha (2011, 2012).
