Inhalt:
A laboratory-based study was carried out to assess the performance and unique intelligence capabilities of an extreme wide-band 10-50 GHz SAR. Very high resolution range-profile measurements were obtained of samples used in building construction. Periodic features in reflectivity with frequency were interpreted as a resonance between the front and back face reflections of a sample. The feature’s characteristics were in good agreement with the idea of a sample as a resonant microwave cavity. The resonance behaviour was preserved in SAR imaging of the samples, examined by sub-band analysis. Selecting a composite Perspex-MDF target, there was good agreement between simulation and measurement.
