Spatially dense maps of topographic height are obtaned by exploiting pixels of SAR interferograms characterized by high values of coherence and applying kriging interpolation to generate regular-grid maps.

A SAR system is a coherent active microwave device able to provide 2D refractivity images of a given area with high spatial resolution, independently of weather conditions and day-night cycle. SAR interferometry is the most notable application of SAR technology. This technique relies on the processing of a time series of coherent SAR images. It gives a powerful tool to produce maps of deformations occurring in infrastructures (dams, buildings, bridges) or terrain. In the last few years the research activity of several remote sensing groups has dealt with the development of GBSAR systems. GBSAR sensors represent a cost-effective solution for the continuous monitoring of small scale deformation phenomena if compared to space and air-borne systems. These systems basically consist of a CW radar mounted on a sliding support and synth...
