Alpine Snowpack Permittivity Retrieval in Forward-Looking Bistatic Radar (Bizona) Configuration
Résumé
This paper presents a method for multi-layered snowpack vertical profile characterization using a low complexity portable MIMO bistatic radar system. An iterative procedure based on calculating the electromagnetic distance which takes into account the refractive index of each layer is proposed. It estimates the refractive index from the snowpack top to the bottom layers. Furthermore, experimental radar measurements performed at the Col de Porte, in the french Alps, is backed up by in-situ stratigraphic samplings provided by Météo France and which are used as a reference. The obtained results are anaylsed and discussed.
