IDS GeoRadar is a leader company who provides products and solutions for geophysical, mining, civil engineering and security applications. Founded in 1980 as part of IDS Ingegneria dei Sistemi in Pisa, Italy, the company was recently acquired by Hexagon. Through a continuous commitment to research & development, IDS GeoRadar provides innovative products using state-of-the-art technologies and novel solutions in the fields of , among the others, Geology and Environmental Management, Archeology, Forensics, Landslide monitoring and Mining safety.
Ground-based radar interferometry (GBRI) is a remote sensing imaging technique based on coherent radar systems, which can measure not only the amplitude, but also the phase of the microwave signals. The phase measurements can then be exploited to derive information on the deformation and topography of the measured scene.
In the last decade GBRI has gained an increasing interest as a deformation measurement and monitoring tool, and currently is a well-established technology, usually exploited by geophysicists, engineers and geotechnicians. Thanks to its high sensitivity to small deformations, its long range of measurements (up to several kilometres) and its imaging capability, GBRI is complementary to many other existing deformation measurement techniques.
In the first part of this lecture the working principles of the GBRI technique are presented: starting from the radar and interferometry basics, we will discuss the fundamentals steps of data acquisition, processing and analysis, then we will finish presenting the different systems and technologies currently available.
In the second part of this lecture a review of the various GBRI applications will be provided: starting from the classic structures, landslide and glaciers deformation monitoring, up to the most recent integration with other measuring system, displacement vector reconstruction, blasting and underground monitoring.
Dott. Alberto Michelini
After studying theoretical physics at the Scuola Normale Superiore of Pisa (2002-2011) he joined the IDS GeoRadar R&D team. His main activities are focused on the development of interferometric radar systems, with a particular interest in data analysis, data processing and exploitation of new technologies.
