Webthe Sigsbee velocity model [5] which is implemented by minimizing the di erence between computed and measured data on the boundary. It is thus a PDE-constrained optimization. There are various kinds of numerical techniques that are used in seismic in-version, but FWI is increasing in popularity even if it is still facing three main WebMar 12, 2024 · Then, a new imaging condition based on the down- and upgoing wave fields and a new weighting function are proposed to suppress RTM artifacts. The proposed imaging condition can suppress artifacts for each reflection angle independently. Finally, the proposed RTM procedure is tested using BP and Sigsbee velocity models.
