Calibration of the mono-static stepped-frequency GPR with a Vivaldi UWB antenna
The mono-static stepped-frequency Ground Pene-trating Radar (GPR) with A Vivaldi Ultra-Wide Band (UWB)antenna was used to non-destructive estimate the parameters (permittivity,conductivity and thickness) of each layer of a stratified subsurface medium.In this realization,a calibration procedure is necessary.This paper introduces the principle and the implementation ofThis calibration. The non-directive property of the Vivaldi antenna makesA challenge of the calibration of the system,because the measurement results are heavily disturbed by reflections from surrounding objects inair. However,after a suitable calibration,it can be used successfully in this radar configuration,and this was validated by the experiment.
