Ground Penetrating

Ground Penetrating Radar (GPR) is a widely used technology in many kinds of geological survey. It’s a geological method that uses radar pulse to image the surface. It is a non- intrusive method of surveying the subsurface to investigate underground utilities such as concrete, asphalt, metals, pipes, cable etc. To add onto these properties of GPR, here a drone and several sensors, which will make GPR surveys more efficient and accurate. The GPR is mounted over a drone (DJIM600 Pro) which will give more precision in work and exploring difficult areas. A GPR mounted on a drone enables to see the underground surface of ground without compromising safety and providing more efficient surveying. Also, it can be used for surveying in unreachable areas and make our job easier. In order to increase the application level of GPR drone integrated system several sensors such as pressure, thermal, humidity, snowfall, rain, gas, infrared sensors are also mounted. In short, GPR drone integrated system with sensors is the easiest and safe solution for geological surveys, archaeological surveys, weather forecasting etc. Keywords: GPR; geology, drone.

Ground Penetrating

Ground Penetrating Radar (GPR) is a geophysical method that is widely used in geophysical surveys, civil engineering applications, archaeological studies and locating underground utilities or hidden objects. It works by sending electromagnetic (EM) wave into the ground by transmitter and recording the returning signals by receiver. The returning signals bring information about the materials and changes in material parameters at different depths. The changes in dielectric properties () of two adjacent media result in EM wave reflections. In this study, several types of materials with different dielectric properties () are used in order to identify the reflectivity of the EM wave. Results prove that the larger the dielectric contrast, the higher the reflection coefficient thus the stronger the reflection.

The accurate location of underground utilities at a construction site can prevent any damage to the utilities during excavation works. The cost of fixing the damage utilities can be very costly and will reduced the expected profit of the construction works. Therefore underground utility detection using Ground Penetrating Radar (GPR) is important in providing accurate information of the utilities at a construction site. In this study TerraSIRch SIR-3000 GPR equipment have been used to detect underground utility, with a 400 MHz ability which can reach up to 3m depth. RADAN 7 software is used to interpret and analyze the GPR data. Based on the results obtained the GPR equipment is capable of detecting underground utilities such as pipe, cable, shaft, etc.. The detected utilities are then shown in the 2-D and 3-D drawing for better visualization and identification.

Abstract This paper presents a review on Ground Penetrating Radar (GPR) detection and mapping of buried utilities which have been widely used as non-destructive investigation and efficiently in terms of usage. The reviews cover on experimental design in GPR data collection and survey, pre-processing, extracting hyperbolic feature using image processing and machine learning techniques. Some of the issues and challenges facing by the GPR interpretation particularly in extracting the hyperbolas pattern of underground utilities have also been highlighted.

Ideal Dielectric

Within the ground penetrating radar bandwidth the medium is considered to be an ideal dielectric, which is not always true. Electromagnetic waves reflection coefficient conductivity dependence showed a significant role of the difference in conductivity in reflection strength. It was confirmed by physical modeling. Conductivity of geological media should be taken into account when solving direct and inverse problems, survey design planning, etc. Ground penetrating radar can be used to solve the problem of mapping of halocline or determine water contamination.
