Introduction
-
We continue in the Kirchhoff prestack depth
migration calculations.
-
The dimensions of the velocity model, shot-receiver configuration,
methods for calculation of the recorded wave field and the migration
are the same as in the papers by Bucha (2011, 2012)
- We generate recorded wave field
in models composed of two layers separated by one non-inclined
curved interface. The upper layer is
inhomogeneous
with triclinic anisotropy and with a vertical or horizontal
velocity gradient.
-
Our aim is to study the influence of a simple
heterogeneity on the migrated image.
