## Kirchhoff prestack depth scalar migration
of complete wave fields in a simple velocity model
with triclinic anisotropy: PP, PS1 and PS2 waves

**Vaclav Bucha**
### Summary

We test 3-D ray-based Kirchhoff prestack depth scalar migration
and calculate migrated sections in a simple anisotropic velocity
model. The velocity model is composed of two homogeneous layers
separated by a curved interface. The upper layer has triclinic
anisotropy and the bottom layer is isotropic. The synthetic
complete seismic wave field is calculated using the Fourier
pseudospectral method. We apply a scalar imaging to each component
of the complete wave field in a single-layer velocity model
with the same triclinic anisotropy as in the upper layer
of the velocity model used to calculate the recorded wave field.
We display and discuss resulting migrated sections.
