In this paper we adopt the similarity principle to study GPR response to voids under road surface or in the levees and dams by cross-examination of GPR data acquired using both high-frequency antennas on laboratory bench-size models and low-frequency antennas in the field. In physical world the similarity principle is widely used in theoretical study and engineering practice. In short, by the similarity...
Application of the finite-difference reverse time migration (FD-RTM) to ground penetrating radar (GPR) data may generate high-resolution imaging for complex geologic bodies. However, in conditions of complex topography, due to topographic roughness it is very difficult to get clear images of near-surface internal structure with the traditional approach of “static correction + flat datum migration”...
