WebMar 5, 2024 · This increase of non-uniqueness rate can be remedied by joint inversion based on (1) Gramian constraints or (2) joint focusing stabilizers. The Gramian constraints enforce shared earth structure through a correlation of the model gradients. The joint focusing stabilizers also enforce the structural similarity and are implemented using … WebOct 28, 2024 · 3D inversions, especially for potential field data that do not have the resolution of depth, are subject to severe non-uniqueness problems. While the non-uniqueness can be mathematically overcome by regularizations, a joint inversion of multiple geophysical datasets can significantly constrain the inversion model on a physical basis. …
