Monitoring of Structural Changes by Radar Interferometry.
In this paper we report the results of a feasibility test on the applicability of Synthetic aperture Radar (SAR) interferometry for monitoring of structural changes. The experiment has been performed in controlled environment on an artificial target made up of reinforced concrete elements. SAR imaging techniques allow the mapping of the object under test with a spatial resolution in the order to few centimeters while the use of differential interferometric techniques allow the measurements of the displacement of each pixel in the image with an accuracy in the order of a small fraction of the wavelength of the radiation used. The achieved results validate the technique as an useful tool which may complement optical or in-situ measurements techniques for industrial application as monitoring of large man-made structures.
