Least-Squares Reverse Time Migration Using the Gradient Preconditioning Based on Transmitted Wave Energy
A gradient preconditioning approach based on transmitted wave energy for least-squares reverse time migration (LSRTM) is proposed in this study. The gradient is preconditioned by using the energy of “approximate transmission wavefield,” which is calculated based on the non-reflecting acoustic equati...
