A method integrating a non-stationary random field for constrained inversion of CSAMT data

ObjectiveThe inversion of controlled-source audio-frequency magnetotelluric (CSAMT) data remains challenging due to two key issues: computational efficiency and resolution. To tackle these two issues, especially the over-smoothing effect caused by traditional regularization methods in estimating com...
