Abstract: In order to reduce the influence of magnetic polarization currents on inversion result, when applying time-domain airborne electromagnetic method(AEM) in areas with high magnetic permeability, we present a new algorithm in this paper. We achieve it by adding the partial derivative of full-time AEM responses with respect to the magnetic permeability into Jacobi matrix and inverting the resistivity, magnetic permeability and thickness simultaneously. We have tested the effectiveness of our algorithm by inverting the responses with Gaussian noise of a series of typical models, such as the magnetic homogeneous half-space model, a single or multi-layer with high permeability in a layered model, and all with RMS (root-mean-square) error below 3%. The results demonstrate that our algorithm can be used to obtain the underground electrical structures in areas with high magnetic permeability.

Key words: time-domain, airborne EM, resistivity, magnetic permeability, inversion
