14th International Conference on Ground Penetrating Radar, 2012

- The oral presentations were held in the 12 sessions. In Session 1, Novel GPR System and Antennas focused on the significant developments in GPR system, GPR survey methodology, development of radar antenna, development of handheld GPR and robot mounted GPR. Session 2 was on the use of radar waves in planetary exploration and was entitled, SAR and Planetary exploration. The session 3, GPR Wave Interaction with the Earth, was focused on the use of the GPR for soil permittivity evaluation and propagation characteristics of EM waves in fractured media. In Session 4 entitled, Data Processing and Interpretation, significant improvements in the GPR data processing methods, GPR identification of voids inside concrete and accurate thickness estimation of backfill grouting layer behind shield were highlighted. Session 5 focused on GPR application in the various fields of Sedimentology and Hydrology, many issues like the use of GPR in the estimation of soil water content, characterization of stratigraphy, estimation of density of ice, study of volcanic surge deposits and aeolian dunes and others were discussed. Session 6 was on the application of GPR in the field of Archaeology entitled, ArchaeologyDiagnosis of historical buildings and described the use of GPR in diagnosis of historical and cultural objects. Session 7 on Numerical Modeling, illustrated qualitative model of spatio-temporal radiation pattern of GPR antenna, numerical simulation and analysis for airborne GPR. Session 8 on Geology/Geotechnical Engineering, Utilities Detection and Mapping, exploring the GPR application in the Geology and the Geotechnical Engineering. Session 9 entitled, Inverse Problems, was focused on the multiparameter spectral inversion for GPR signals of subsurface layered media and full waveform inversion of GPR data in frequency domain. Session 10 on Evaluation of Mining, Tunneling, Concrete and Pavements, focused on new developments in the use of GPR in mining and tunneling. Session 11 on Borehole Radar included presentations delivering the information on the borehole radar prototypes, analysis of a direct wave in directional borehole radar, electromagnetic wave transmission characteristics research of single-borehole radar, etc. Session 12 titled, Demining, UXO & Human vital sign, describing the performance of a demining GPR related to soil properties and clutter, 3D segmentation of GPR data for landmine detection and application of the stepped-frequency continuous wave radar technique for detection of human cardiorespiratory signals. The following four keynote lectures were presented: 1. Prof. Yaqiu Jin (Fudan University, China): Simulation of radar sounder (...truncated)
