Three-Dimensional Inversion of CSAMT Tensor Impedance Data

摘要

Tensor CSAMT is an effective method of electric prospecting applied in geologically complex regions because of its high signal-to-noise ratio and rich geoelectric information.A three-dimensional forward problem of tensor CSAMT has been solved through staggered-grid finite difference method,based on control equation of electric field with electric source-current density.Furthermore,a tensor CSAMT three-dimensional data-space inversion algorithm has been accomplished and a set of synthetic data has been test.This inversion algorithm turns out to be valid and practical.
