A Novel Approach for Qualitative Imaging of Buried PEC Scatterers
Abstract: A new linear
approach for support reconstruction of impenetrable objects is described and
tested in case of scattered field data collected in Ground Penetrating Radar
measurement configuration. Starting from the considerations that in high
conductivity scatterers the currents induced inside the scatterers are only
localized on its boundary and that they take up only few pixels of the entire
investigation domain, a sparsity promoting inversion technique is formulated.
The flexibility of the approach allows counteracting the specific difficulty to
work under aspect limited measurement configurations, as the one at hand. Examples
with numerical noisy data are given to demonstrate and validate the
effectiveness of the method in localizing and in retrieving the shape of the
unknown objects buried in lossy soil.
Keywords: antennas, inverse
