Synthetic-aperture radar system and operating method for monitoring ground and structure displacements suitable for emergency conditions

摘要

A synthetic-aperture radar system, and related operating method, for the monitoring of ground and structure movements, particularly suitable for emergency conditions, characterized by a ground based platform with polarimetric capabilities, that able to quickly acquire, embeddedly process and post-process data by a novel data acquisition "On the Fly" mode of operation, reducing by at least an order of magnitude the data acquisition time. The inventive system characteristics allows to achieve on-field measurement results on three-dimensional maps georeferenced to absolute coordinate systems (WGS84, Gauss-Boaga, and so on). The operating method includes the step of installing the system, the acquiring of the first measurements, the quick data processing and post-processing to provide sub-millimetric precision georeferenced bi-dimensional and three-dimensional displacement maps for the objects belonging to the monitored scenario, with an improved performance and in a measurement time compatible to that required in an emergency condition, with an higher degree of integration with other sensors and autonomously and embeddendly.
