| Zusammenfassung |
Ground Penetrating Radar (GPR) is an electromagnetic technique very
appreciated by the community of the archaeologist and cultural heritage
end-users community thanks to its appealing features in terms of non
invasivity and rapidity of measurement and diagnostics. However, GPR data
requires a high operator expertise in the data processing and
interpretation. In the archaeological investigation, this drawback can be
mitigated by the availability of a priori information about the
archaeological scenario. On the other hand, in the case of the historical
heritage, when the knowledge of constructive modalities and material of the
structure may be completely missed, it is necessary to undertake other
strategies of processing and interpretation.
One of these can be provided by the use of novel inversion algorithms such
as the Microwave Tomography (MT) which allows to reduce the subjectivity and
the time consuming during the data processing. In this paper the MT was
applied on raw data collected at two historical buildings of Chania (Crete,
Greece). The first edifice is the Venizelo's House affected by visible
fractures in its walls made up of cemented irregular stones. The second one
is the headquarters of Prefecture of Chania showing some fractures along the
floors. For these raw data, microwave tomography provided well detailed
images which allowed to infer the fracture geometry and their extension in
the host medium. This suggests microwave tomography can be a reliable
complete processing tool requiring only the definition of the background
scenario in terms of the dielectric permittivity and the conductivity of the
host medium. |
