Caracterisation Electromagnetique in-Situ De Sols En Bande L. Application a L'Identification De Profils Geologiques

The development of instruments for remote sensing applications (active or passive) requires in situ validation measurements. The equipments (radar or radiometer) must be tested on real geological profiles. We must have accurate information on the profiles studied (permittivity, humidity, thickness of layers …). Sensors (humidity), samples (thickness) or laboratory measurements (permittivity) provide local data about the profile while the remote sensing equipment is performing global measurements on a geological structure. The present work describes an in situ characterization bench test, based on two horn antennas, associated with an identification profiles software we developed to obtain comprehensive and instantaneous information on the geological profiles.
