INVERSION USING A FILTERING OPERATOR

INVERSION USING A FILTERING OPERATOR

To perform inversion to produce a model of a structure, a filtering operator based at least on an angle between a propagating direction of a source wavefield and a propagating direction of a back-propagated receiver wavefield is computed. The filtering operator is used in performing the inversion to...
