Abstract
Summary
Ground Penetrating Radar (GPR) data may include not only signal events originated by real features present within the investigated materials, but also some artifacts caused by additional and not easy to predict travel paths or by elements located adjacent or above the scan line. A good understanding of the wave behavior and accurate observations on site are therefore necessary and mandatory for a correct interpretation. This paper presents five case-studies where unwanted and unexpected signatures produced by structural and non-structural metal elements and overhead objects are discussed and analyzed.
