The detection and identification of buried materials (e.g.weapons, explosives) are routine practices in various forensic investigation scenarios, ideally occurring in an expeditious and safe manner. Due to its non-invasive nature concerning the geological matrix where the materials may be buried, forensic geophysics enables a fast response to this kind of needs. In many countries, explosive devices are a threat to public safety, their detection and identification being unexpendable for the subsequent removal and destruction under ideal safety conditions. Consequently, the current study aims to analyze the versatility of two georadars (2D-Easyrad and 3D-radar) in order to meet the above mentioned needs. For that purpose several scans will be processed with the two equipments, both in a soil and a sediment, during the 4 seasons of the year and against variables related to the explosive device (type,shape and size). The main aim of this project is the development of certified protocols suitable for the characteristics of the national soils and sediments in order to be implemented, by police and military forces, in real cases involving the detection of underground explosive devices.
