Abstract—A realistic model of ground soil is developed for the electromagnetic simulation of Ground Penetrating Radar (GPR) systems. A three dimensional Finite Difference Time Domain (FDTD) algorithm is formulated to model dispersive media using N -term Debye permittivity function with static conductivity. The formulation of the algorithm is based on the concept of the Piecewise Linear Recursiv...

The detection of embedded object from ground penetrating radar GPR imagery is our goal. The GPR image is a cross sectional slices. The embedded objects are metal and/or plastic type. In many fields demand for visualizing objects scanned as cross sectional slices is growing. This research has many real world applications, such as robotic environments, medicine, remote sensing, inspection of indu...

ground penetration radar (gpr) as a nondestructive method for identifying underground objects has been successfully applied to different fields of science such as geotechnical investigations, oil and gas exploration, geology, pipe detection and archeology investigations. metallic and nonmetallic objects can be identified by this method.  the depth of penetration is dictated by the gpr antennas....

Ground penetrating radar (GPR) systems are sensors that able to acquire underground images by scanning the surface of soil/pavement under investigation. Usually, a GPR system records its own position along scan line, using mechanical odometer, i.e., rolling wheel in contact with ground. This simple and cheap solution can be ineffective on uneven terrains. In this paper, positioning based an int...

Continuous seismic-reflection profiling (CSP) and ground-penetrating radar (GPR) surveys were conducted by the U.S. Geological Survey in April 1998 over the northern part of John’s Pond, a glacial kettle pond southeast of Otis Air National Guard Base, Cape Cod, Massachusetts. The surveys were conducted to delineate the types and thickness of sedimentary units that may control the infiltration o...

The defect investigation of sluice floor is an important measure to ensure the safe operation sluice. due traditional drilling methods will cause damage floor, and appearance inspection compressive strength test can not evaluate internal defects reinforced concrete in floor. In this paper, we apply ground penetrating radar(GPR) quality a gate seawall. And describe layout, detection principle da...

This paper addresses the problem of inverting Ground Penetrating Radar (GPR) data, to find the buried inclusions characteristics depth and radii considering a nonhomogenous host media by using neural networks (NN). The aim is the detection and characterization of inclusions in concrete structures. A novel asynchronous model is proposed to the NN arrangement. The model is shown to outperform the...

Ground-reßected clutter is often a performance-limiting factor in ground-penetrating radar (GPR) detection of nearsurface targets including anti-personnel mines. When a down-looking antenna is scanned across the surface this reßection produces a strong band in the image, which obscures shallow targets. Imperfections in the system impulse response (e.g., antenna ringing and cable reßections) can...

We present a ground penetrating radar (GPR) system, which uses an antenna array for in situ measurements of the thickness and dielectric permittivity of an asphalt pavement layer. We calibrated the antenna array by considering the antenna phase center and the antenna offset. The results of the laboratory measurements demonstrate that the proposed calibration method can greatly improve the accur...
