Radar interferometry is an image processing technique based on the phase difference between two radar images taken at different times in two neighboring orbits or two simultaneous acquisitions.
Radar interferometry is a satellite observation technique with applications in geophysical fields as varied as volcanology, seismology, glaciology, urban subsidence and landslide. In urban environment, it makes it possible to characterize the vertical deformations of the soil of small amplitude (typically from a few millimeters to a few centimeters) over large areas.
The Sentinel 1A and 1B satellites are a family of Earth observation satellites launched respectively in April 2014 and April 2016. Data from these satellites can be downloaded free of charge from https://scihub.copernicus.eu/dhus/#/home .Sentinels-1A and 1B are equipped with Synthetic Aperture Radar (SAR) providing high spatial resolution (10 m) images with a 6-day temporal resolution. The duration of the Practical Training on Radar interferometry and its applications is ten days. A Presential training of one Day (face-to-face) and nine days of distance training via e-learning platform (http://rifgeomatique.com/moodle/ ) and GOOGLE DOCS technology (Collaborative online work).
Software used in training: SNAP, QGIS, Snaphu.
