Large-scale focusing joint inversion of gravity and magnetic data with Gramian constraint
Large-scale focusing joint inversion of gravity and magnetic data with Gramian constraint
A fast algorithm for the large-scale joint inversion of gravity and magnetic data is developed. It uses a nonlinear Gramian constraint to impose correlation between density and susceptibility of reconstructed models. The global objective function is formulated in the space of the weighted parameters, but the Gramian constraint is implemented …
