Experimental Data of Research Using Ground-Penetrating Radar “Zond-12c” and Interpretation of Georadarograms

Abstract

The paper presents engineering methods for the interpretation of georadarograms. For this purpose experimental research using ground-penetrating radar “Zond-12c” were carried out, in which artificial objects, placed in the training laboratory ground, were studied. The aim of the research is the geophysical investigation of the structure of lower layers and presence of artificial objects for obtaining of analogy georadarograms. The experiments allow developing of technology for the interpretation of real ground-penetrating radar data from unknown objects. Experiments also allow us to solve the inverse problem of determining the geoelectric properties of environments [S.I. Kabanihin, K.T. Iskakov, M.A. Bektemesov, M.A. Shishlenin, Algorithms and numerical methods for the solution of inverse and ill-posed problems, Astana 2011 (in Russian)]. Application of ground-penetrating radar in restoring of the structure of the underground environment can be reduced to the solution of ill-posed problems for hyperbolic and parabolic types of equations. Many researchers describe algorithms for this kind of problems. At present, methods of interpretation of georadarograms can be improved by new achievements of the inverse problems theory. The bottleneck of application of the ground-penetrating radar is the complexity of interpreted data, requiring at the present stage to attract highly qualified professionals. Forming of own methods of interpreting ground-penetrating radar data contributes to preservation of confidential geophysical information.
