Abstract
In the last decades systematic excavations and Heritage valorization programs has been developed in the Motilla del Azuer Bronze Age archaeological site by University of Granada Department of Prehistory and Archaeology. Two geophysical research activities have been the most recent made, in 2009, in order to prioritize the areas where the future excavations campaigns could take place. Ground Penetrating Radar (GPR) in 3D mode has been used. The site shows a conical mound shape and has important layers of collapse. Both factors (slope and collpse) produce blurry images GPR which don’t make easy any archaeological interpretation. In this paper strategies to get radar images as good as possible are discussed, such as topographic correction of data, design of warped surfaces and three-dimensional image in order to discard the levels of collapse.
