Up: Sava and Biondi: WEMVA
We construct 2D and 3D sensitivity kernels for wave-equation MVA and
study their dependence with respect to the data source,
the frequency content, and the type of image perturbation.
Sensitivity kernels illustrate the complications of wave propagation
in the cases of rough salt bodies and the frequency-dependent
illumination subsalt. With this type of analysis, we
also illustrate some of the reasons why traveltime
tomography is less than ideal for subsalt velocity analysis.
