Abstract

Several authors have published different expressions for the pseudo-inverse operator in the case of the subsurface extended Born modelling. We review here the principles to establish such inverse operators and show the close relationships between them. With one of the strategy, we then illustrate how triplicated wave fields can be properly handled and how the inverse operator can be incorporated as a preconditioner for least-squares migration in the extended domain.
