Smooth objective functionals for seismic velocity inversion ∗

Abstract

In seismic inverse scattering, the data are divided into subsets, each of which is used to reconstruct the medium discontinuities by linearized inversion. The reconstructions depend on an a priori unknown, smoothly varying background medium (velocity model). The semblance principle, which states that the images must agree, is the basis for the… (More)
