Abstract: Since Airborne Electromagnetic（AEM）survey produces massive data,an effective imaging and inversion tool is very important.In this work,we take a layered earth model as an example to derive the one-dimensional（1D）time-domain AEM inversion under generalized model constraints.Starting from the objective functional for the regularized inversion,we establish the Lp-norm inversion and focusing inversion by changing the model constraints,and the sparse constraint inversion based on wavelet transform by... More
