Satellite SAR Interferometry is a technique for the measurement of ground surface displacements. By radar images, collected by satellites on the same area, it is possible to measure millimeter displacements of ground and structures. Last generation algorithms developed by NHAZCA allow customizable applications of the technique for different purposes.
The recent advanced interferometric techniques (A-DInSAR) exploit the presence of natural reflectors (such buildings, infrastructures, rocks etc.) to provide reliable points for accurate displacement measurement.
NHAZCA provides customized and reliable solutions, making available to the clients its proven experience in the field of geotechnical and structural monitoring and its strong expertise in advanced satellite SAR data analysis.
NHAZCA is a reference partner for the study and characterization of surface processes in the territory, both at the local scale (as a single structure/infrastructure) and regional scale (whole cities or large areas).
Thanks to the historical archives of images (available since 1992), to the present space missions and those planned for the near future, NHAZCA performs historical displacement analysis (thus providing quantitative data also in areas where no monitoring equipment was installed in the past) and provides monitoring services for the control of the present evolution of the investigated phenomena.
Moreover, NHAZCA can process a wide range of satellite SAR data, characterized by different technical specifications and, therefore, suitable for different fields of application like ERS1 and ERS2, ENVISAT, RADARSAT-1, RADARSAT-2, ALOS-PALSAR, ALOS2, TerraSAR-X, COSMO-SkyMed, SENTINEL-1A, SENTINEL 1-B.
