Le radar mural : un nouvel outil pour l'archéologue du bâti

Abstract : New tools such as photogrammetry or 3D scanner surveys have revolutionized the way of understanding the archaeological study of a building. These tools are now commonly used but, when the walls of a building are covered by a plaster, the visual observations are considerably more complex. The implantation of observation windows to be pitted can prove to be a delicate exercise and potentially not representative of the part of the building to be studied. Geophysical techniques and more particularly the radar method can partly guide this approach thanks to the preliminary realization of an extensive wall imaging. They can also be a precious help for the setting up of scientific projects of building excavations by giving an overview of the surfaces not probed during the diagnosis. This type of analysis is based on the use of very high frequency radar (>2 GHz). These radar antennas, initially developed for civil engineering, allow the inspection of concrete and the evaluation of its quality. When the surface of a wall is sufficiently smooth, the realization of a dense mesh of measurement allows very quickly to auscultate the wall on a few decimeters of thickness with a very high resolution. Old features can then appear such as blocked openings or differences in blocking. These themes are still very little developed but a strong potential exists. Inrap’s geophysics and remote sensing unit is currently working on this theme to improve building studies. Following a first test carried out at the Abbey of Ferrières-en-Gâtinais (45), we will show here the potential of the method and the various applications which can result from it to help the work of the archaeologist of the building. A PAS research project has been submitted in 2021 to associate geophysicists and archaeologists on this research theme directly related to the operational.
