processing and interpretation of ground penetrating radar (gpr) data in order to determine thickness and basement topography of alamkooh glacier
determination of the thickness of a mountains glacier like alamkooh is very difficult due to its extremely cold climate conditions and high elevation, risk of falling large snow segments or balls and coarse topography of the glacier. in this research, due to the transparency of ice for electromagnetic (em) waves, and also, that ground penetrating radar (gpr) method is non-destructive, fast and ...
متن کاملTheory of ground-penetrating radars III
The governing equations are Maxwell’s. The source of the current is either j = ey δ(z − z0)δ(x)f(t) or eφ δ(z − z0)δ(r − r0)f(t) (straight wire or loop of current, f(t) is a pulse). The conductivity σ(z) and permittivity ε(z) are unknown in the medium (z > 0) and are known in the air (z < 0). The source is in the air: z0 < 0. The μ is a known constant. The data are the values of E(x, y, z, t) a...
متن کاملImage Processing and Neural Network Techniques for Automatic Detection and Interpretation of Ground Penetrating Radar Data
Ground penetrating radar (GPR) has gained a distinguished place during recent years as a tool for investigating subsurface objects, yet its output is of low resolution, and in need of further processing in order to make its output readily interpretable. Furthermore, GPR data collected in a typical survey is usually in large quantities, and dealing with such quantities manually to produce final ...
متن کاملGround-Penetrating Radar Mapping Using Multiple Processing and Interpretation Methods
Ground-penetrating radar processing and interpretation methods have been developed over time that usually follow a certain standard pathway, which leads from obtaining the raw reflection data to the production of amplitude slice-maps for three-dimensional visualization. In this standard series of analysis steps a great deal of important information contained in the raw data can potentially be l...
متن کاملSimulations of ground-penetrating radars over lossy and heterogeneous grounds
The versatility of the three-dimensional (3–D) finitedifference time-domain (FDTD) method to model arbitrarily inhomogeneous geometries is exploited to simulate realistic groundpenetrating radar (GPR) scenarios for the purpose of assisting the subsequent designs of high-performance GPR hardware and software. The buried targets are modeled by conducting and dielectric prisms and disks. The groun...
