First Claim
1. A synthetic aperture radar system for monitoring ground and structure movements, said system comprising at least the following mechanical and electronic components:
- a ground based platform including a measurement interferometric and polarimetric sensor, an embedded power supply and connection unit, a linear positioner provided with a movable carriage, and a measuring head;
an embedded main system control unit, an embedded electromagnetic wave generator and receiver module controlled by said unit, comprising a continuous—
wave stepped—
frequency scatterometer, a motor control and managing unit, an embedded UPS module including an embedded buffer battery;
an I/O managing module, an embedded calibrated videocamera or photocamera, an embedded. GPS receiver module, an embedded display and an alphanumeric keypad, an embedded LAN module, an embedded mass storage module, an embedded GSM/GPRS/UMTS module, an embedded WLAN module, and embedded standard interfaces for assembling laser scanners and topographic instrument reflectors;
whereby all the mechanical components of said system are provided with unique reference marks and points or connections, characterized in that, to perform a measurement, said measuring head is initially driven along a linear track with a constant speed in an “
on the fly”
acquisition mode of operation; and
wherein during a constant speed movement, the system acquires data needed to process a single radar image.

Abstract
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.
