Abstract :
This paper presents a method, based on ground penetrating radar (GPR) signal processing in the frequency domain, to estimate moisture content in a porous medium without preventive calibration. Several indicators based on high order moments are extracted from the GPR spectra and their dependency on the moisture content is evaluated. Experimental results confirm the theoretical expectations and show the effectiveness of the proposed approach to estimate soil moisture content.
