Analysis and Calibration of Ground Penetrating Radar Shielded Antennas

Abstract: Ground-Penetrating Radar (GPR) is a non-destructive geophysical method applied in many civil engineering applications. The knowledge of the GPR antennas behavior is crucial to obtain accurate results and comprehensive data interpretations. However, the age of the antennas and the use can modify the values provided by manufacturers. Consequently, calibration of antennas is recommended. Calibration involves determining several parameters. In this paper, the evaluation of two parameters (stability of the signal a… Show more

“…In general, the field area has to be inspected, and objects that could prevent adequate data acquisition or affect the GPR signals should be assessed and removed, where possible. Obstructions such as metallic objects, vehicles, vegetation, livestock, and underground infrastructure, [53,80] can all impede the successful conclusion of a GPR survey. The problem of underground infrastructure is especially relevant in urban areas and particularly when the buried infrastructure is not the focus of the investigation.…”

“…This instrument consists of a wheel with an odometer that was previously calibrated, along a 10m radar line, travelling in both directions. However, the calibration of the stability of the antenna prior of the field data acquisition is recommended frequently since the use and age of the antenna can deteriorate them and modify antenna behaviour (M. Pereira et al, 2005;M. Rasol, Perez-Gracia, & S.Assuncao, 2018).…”
