GPR Measurements for Utility Detection
摘要
Ground Penetrating Radar (GPR) is a geodetic-geophysical method used for subsurface utility detection and mapping. This paper presents an overview of GPR principles, applications in utility detection, and key factors influencing the accuracy and precision of measurements. Radargrams from utility surveys, including gas pipelines, telephone cables, and sewer systems, are analyzed to illustrate practical outcomes. Using the Leica DS2000 georadar, various frequencies, grid orientations, and scanning parameters were evaluated. This study emphasizes GPR’s role in non-destructive utility mapping and highlights considerations for improving detection accuracy.
