## Kirchhoff prestack depth scalar migration
of complete wave field in a simple inhomogeneous
weakly anisotropic velocity model: preliminary tests

**Vaclav Bucha**
### Summary

We use 3-D ray-based Kirchhoff prestack depth scalar migration
to calculate migrated sections in a simple inhomogeneous weakly
anisotropic velocity model.
The complete seismic wave field is calculated using the Fourier
pseudospectral method.
Velocity model is composed of two layers separated
by a curved interface.
The upper layer is inhomogeneous weakly anisotropic and the bottom
layer is isotropic.
We apply 3-D Kirchhoff prestack depth scalar migration to
single-layer velocity model with the same weak
anisotropy as in the upper layer of the velocity model
used to calculate the recorded wave field. We show and discuss
the first results of the migration for complete wave field.
