dc.description.abstractWe present a new target-enclosing full waveform inversion (FWI) method based on a interferometric objective function, where the inversion is driven by the misfit between the wavefields reconstructed in a subdomain of interest via the convolution and correlation representation formulas. The method is fully local in the sense that it does not depend on the reconstruction of the physical properties outside the local domain, and only requires a kinematic velocity model estimate for redatuming. We compare the proposed method to another fully local FWI method based on the convolution representation formula and to full-model surface-data FWI. We demonstrate the potential of the proposed interferometric full waveform inversion method to achieve higher resolution images at a comparable or lower cost than the other methods.
