Foreword

It is our great pleasure to present the Proceedings of the 15th International Conference on Ground Penetrating Radar (GPR 2014), held in Brussels, Be lgium, from June 30 to July 4, 2014. The International Conference on Ground Penetrating Radar is a longstanding traditional event making the premier forum of research and applications in the field of GPR. GPR 2014, the 15th in the series that has been held biannually since 1986, has brought together 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. Topics covered include novel developments of GPR systems and antennas, advanced data processing algorithms for improved subsurface imaging, radar data modeling approaches and inversion strategies for quantitative reconstruction of soil and material properties, and finally, data interpre tation in a range of fields, including geology and sedimentology, glaciology, environmental and agricultural engineering (e.g., hydrological monitoring, digital soil mapping, forestry), civil and military engineering (e.g., utility detection, monitoring of transport infrastructures, nondestructive testing, landmine detection), archeology and cultural heritage, and planetary exploration, among others. GPR 2014 is in particular co -organized with EU-COST (European Cooperation in Science and Technology) via the Cost Action TU1208 “Civil Engineering Applications of Ground Penetrating Radar”
