Micrometric deformation imaging at W-Band with GBSAR
The paper presents the experimental evaluation of 94 GHz CW-FM Radar that can be configured as a Ground Based SAR (Synthetic Aperture Radar) for high resolution imaging and deformation control. This system has been designed to obtain and analyze data of deformations on different types of bodies, being able to detect range changes of the order of micrometers. After indoor testing and validation ...
متن کاملGround-based SAR data analysis tools for deformation monitoring
In the last years, the Ground-Based SAR (GBSAR) technique has proved to be a reliable tool for deformation measurement and monitoring. Compared with other point-wise geodetic techniques it can provide “continuous” displacement measurements over areas of few squared kilometers, with a high spatial resolution and precision up to millimeter level. The process of estimating deformation from the GBS...
متن کاملVision-Based Bridge Deformation Monitoring
Optics-based tracking of civil structures is not new, due to historical application in surveying, but automated applications capable of tracking at rates that capture dynamic effects are now a hot research topic in structural health monitoring. Recent innovations show promise of true non-contacting monitoring capability avoiding the need for physically attached sensor arrays. The paper reviews ...
متن کاملVolcano Deformation Monitoring Using GPS
Volcanic eruptions are often very destructive events, having a massive impact on the natural and human environment. In order to mitigate the effect of volcanic hazards such as pyroclastic flows, lahars and tsunamis it is necessary to closely monitor volcanoes. Ground surface deformation is recognised as a reliable indicator of an impending eruption and can give clues to magmatic processes at de...
متن کاملGround-based SAR interferometry as a supporting tool in natural and man-made distasters
In this work we present some applications of Ground-Based Synthetic Aperture Radar (GBSAR) interferometry to the monitoring of dams, bridges and landslides. 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 applicat...
