Foreword to the Special Issue on Advances in Ground-Penetrating Radar Research and Applications

This Special Issue in IEEE JOURNAL OF SELECTED TOPICS IN APPLIED EARTH OBSERVATIONS AND REMOTE SENSING (IEEE JSTARS) on Advances in Ground- Penetrating Radar Research and Applications is organized in the frame of the 15th International Conference on Ground Penetrating Radar (GPR 2014), held in Brussels, Belgium, from June 30 to July 4, 2014 (http://sites.uclouvain.be/GPR2014/). This International Conference is a longstanding traditional event making the premier forum of research and applications in the field of ground-penetrating radar (GPR). GPR 2014, the 15th in the series that has been held biannually since 1986, brought together about 300 high-standard scientists, engineers, industrial delegates, and end-users working in all GPR areas, ranging from fundamental electromagnetics to the so various fields of application. In total, 42 countries worldwide were represented. GPR 2014 was organized by the Université catholique de Louvain (UCL, Belgium) and co-organized by the University of Edinburgh (U.K.), Delft University of Technology (The Netherlands), and Roma Tre University (Italy), together with EU-COST (European Cooperation in Science and Technology) via the COST Action TU1208 “Civil Engineering Applications of Ground Penetrating Radar.” The conference was sponsored by the IEEE Geoscience and Remote Sensing Society, the COST Action TU1208, the Fonds de la Recherche Scientifique(FNRS, Belgium), the European GPR Association (EuroGPR), and 14 private companies which exhibited their products and services during the conference.
