GPR Technologies for Finding and Positioning Subsurface Cracks in Road Surfaces

The paper deals with issues related to the technical possibilities of using modern ultra-wideband ground penetrating radar (GPR) for detecting hidden subsurface defects. Some issues related to the use of ground penetrating radars were also considered in earlier works of the authors, however, in this publication, new results obtained by the authors on the roads of Ukraine are discussed, and the development of this topic is also proposed. The corresponding proposals are based both on the achievements of modern radiophysics and on successes in related fields of science, both technical and applied. The relevance of this topic is evidenced by a significant number of publications, both those that have already become classics and modern ones. The introduction contains an overview of remote sensing methods and a brief analysis of the possibilities of using GPR for road surveys. The conclusion contains an analysis of some of the results obtained in the work and related further developments in this direction.
