Abstract :
Electromagnetic models are fundamental for understanding of the interaction processing between electromagnetic waves and matter and further to retrieve geophysical parameters from observation data. The MEMLS and DMRT are two most widely used models and these corresponding multilayer versions include the effects of stratification due to ice-layer and depth hoar. In order to extend the results Tedesco has obtained, following the Durand´s work, sufficiently comparisons of multilayer model are made in this paper to definitively determine which the better approach is meaningful. At First, we compare the accuracy of MEMLS with multilayer QCA/DMRT using the same multilayer snowpit inputs. Secondly, in order to the stability of model, we test the sensitivity of models.
