Abstract
In the present work, a comparison between Time Domain Reflectometry (TDR) and Ground Penetrating Radar (GPR) measurement on a test site is performed. The finale scope of the experimental study was to explore the possibility to develop a new approach to water content estimation, based on the analysis of the GPR early-time response. Instantaneous amplitude signal of the first 8 ns have been compared with electrical parameters (and dc) extracted from TDR measurements. The tests were conducted in a specifically designed site, in which the soil water content could be varied. The results show a good correlation between the GPR instantaneous amplitude data and soil electromagnetic properties.
