T1 - Non-destructive investigation of complex historic masonry structures with impulse radar T2 - International Symposium Non-Destructive Testing in Civil Engineering (NDT-CE) N2 - For the investigation of the complex inner structure of historic buildings, the application of radar has been increased during the last ten years. Although historic masonry in general is very inhomogeneous and although in some cases high absorption occurs due to enhanced moisture, radar has been successfully applied to get information on geometry, position of inclusions and about kind and size of existing damages. In this paper case studies will be presented concerning the localisation of metallic inclusions and the investigations of the structure of an exterior wall with a multiple leaf structure.
