abstract: This work presents an innovative GPR microwave imaging technique aimed at
retrieving the electromagnetic properties of inaccessible domains buried below a
planar interface. The arising two‐dimensional (2‐D) inverse scattering problem is
solved taking into account for the wide‐band nature of GPR data by exploiting a
multi frequency (MF) solution approach. Moreover, a customized multiresolution
particle swarm optimizer (IMSA‐PSO) is exploited in order to minimize
the MF cost function by adaptively refining the image resolution only in the
identified regions of interest (RoIs). A set of numerical experiments is shown in
order to verify the effectiveness of the developed MF‐IMSA‐PSO technique when
the background permittivity is not exactly known. A comparative assessment
with respect to a deterministic local search‐based microwave imaging technique
is given, as well, to highlight the superior performances yielded by the
exploitation of the PSO solver.
