Full Reciprocity-Gap Waveform Inversion in the frequency domain, enabling sparse-source acquisition
Florian Faucher, Giovanni Alessandrini, Hélène Barucq +3
The quantitative reconstruction of sub-surface Earth properties from the propagation of waves follows an iterative minimization of a misfit functional. In marine seismic exploratio…

Eigenvector Model Descriptors for Solving an Inverse Problem of Helmholtz Equation: Extended Materials
Florian Faucher, Otmar Scherzer, Hélène Barucq
We study the seismic inverse problem for the recovery of subsurface properties in acoustic media. In order to reduce the ill-posedness of the problem, the heterogeneous wave speed…
