Finite difference time domain (FDTD) method is widely used to understand and interpret results of Ground penetrating radars (GPR). Simulation studies using FDTD on response of buried features to GPR is a standard practice. However, quantification of these simulated GPR response, which is required for application to real life problems, is not common. In the present work, several scenarios of pipe buried...
Interpretation of B-scans gathered using a GPR is often difficult. The difficulty can be resolved to a large extent if responses of common objects under different scenarios are known. Finite difference time domain (FDTD) simulation is widely used to understand the response of buried objects to GPR under diverse object-ground scenarios. However, relating these responses to discern inherent patterns...
Some practical situations encountered in civil engineering are detection of buried pipes and manholes in soil or under pavements and characterization of soils at construction sites. Ground penetrating radar is an useful tool for this purpose. GPR data or a radargram is a resultant of interactions between GPR signals at a particular frequency and polarization and properties of host medium (ground)...
Buried object detection is an important and difficult problem. It has significance in civilian situations like excavation of trenches without damage to pipelines to military manoeuvres in mine-laden areas. Often information on buried pipes or mines are unavailable after passage of some time and Ground Penetrating Radar (GPR) is fast emerging as an effective technique for these applications. The results,...
