In this Letter, the authors describe an innovative application of radar interferometric techniques aimed to monitor structural deformations of buildings. The proposed application is based on the use of ground-based instrumentation able to operate as Interferometric Synthetic Aperture Radar (InSAR). Preliminary experimental results on a model of an historical building encourage the development of this technique for use in architectural heritage survey.
