CARACTERISATION ELECTROMAGNETIQUE DE MATERIAUX GEOLOGIQUES EN VUE DU SUIVI DE L'HUMIDITE DES SOLS PAR RADIOMETRIE MICRO-ONDES

Abstract : The work which we present takes place within the framework of mission SMOS of the ESA which will consist to send a radiometer (1.4 GHz) in space. The goal of the research which we propose is the improvement of the comprehension of the effects of structures composed of soil and litter. The effects of the litter and heterogeneities of the ground are probably important but still ignored. The objective of this work was to study the dielectric properties of a type of litter and ground in order to integrate these values into an analytical multi layers model of soil. The objective is to characterize the effects of this layer on the total multi layer system. This will make possible to lead to a simple analytical formulation of a model of litter which can be integrated into the calculation algorithm of SMOS in order to collect information on moisture starting from measurements of emissivity
