The Development of Ground Penetrating Radar (GPR) Data Processing

Abstract

Ground Penetrating Radar (GPR) is one of radar types that is often used to determine conditions inside or below some surface. GPR is also commonly used as a material evaluation tool by its trait as a non-destructive testing (NDT). One of the most important sections of GPR is signal processing system or GPR data processing that will filter all of the GPR survey results. Reflection signals gained by the radar antenna are then filtered to discover any objects located below the ground surface. The better the process in filtering data, the more accurate the GPR interprets the gained signal. This study aims to design a GPR data processing system that is sufficiently be able to interpret the gained signal so that it can accurately discover any objects located on the ground. This GPR data processing system is expected to work on a variety of frequencies and the application can be developed in various types. The aims of this study are designing and modifying the GPR data processing system.

A New Methodology for the Detection and Extraction of Hyperbolas in GPR Images

“…The difference in time results from thermal drift, electronic instability, or variations in antenna airgap. In order to improve image quality and the signal to noise ratio, both time filters (i.e., simple mean, simple median, low pass, high pass, and band pass) and space filters (i.e., simple running average, average subtraction, and background removal) may be implemented [4]. One of the applied filtration processes consisted in conducting the Gain processing which refers to the enhancement of the amplitude and energy of electromagnetic waves, whose power diminishes after dispersion, diffraction, and absorption by the underground medium.…”

“…In order to interpret the obtained radiograms correctly, they have to be subjected to preliminary processing. This stage involves mainly time-zero correction, removing the background, and the migration and extraction of maximum values [3,4]. The aim of processing radargrams is to improve the efficiency of the interpretation process and ultimately to define the position of buried objects.…”
