A comprehensive analysis of electromagnetic (EM) inversion applied to pavem
ent profiling by using a monostatic ground penetrating radar (GPR) is prese
nted. Since in GPR systems using transfers EM (TEM) horns, the antenna is p
ositioned close to the the investigated medium and a strong EM interaction
occurs. This effect is taken into account by modeling the antenna with equi
valent sources placed on the aperture section and by using an accurate EM m
odeling within the inversion loop in order to account for the contribution
of near-field effects.
Experimental results on the antenna modeling procedure and on a pavement pr
ofile estimation validate the feasibility of both the calibration and the i
nverse problem proposed.
