Dispersion is an important effect contributing to attenuating ground-penetrating radar (GPR) signals and must be incorporated in wave propagation. The constant-[Formula: see text] model (quality factor [Formula: see text]) is valid in rocks for typic

A multiscale approach to full-waveform inversion using a sequence of time-domain misfit functions

Autor: Walter E. Medeiros, Jessé C. Costa, Renato R. S. Dantas

Publikováno v: GEOPHYSICS. 84:R539-R551

Most of the approaches designed to avoid cycle skipping in full-waveform inversion (FWI) involve calculating a sequence of inversions in a multiscale fashion. We have adopted an alternative strategy, which is inverting a sequence of different misfit
