| In this work we consider the problem of determining the dielectric
characteristics of sub-surface layers by means of GPR systems. In particular,
a suitable electromagnetic feature (the RΓ parameter), strictly
related to the geophysical parameters of the scenario, is first extracted
from the GPR e.m. signal and then fed to an artificial neural network (ANN)
in order to derive the dielectric permittivity of the sub-surface layer. |
