Deformation measurement with repeat pass airborne interferometry
article
River dikes can deform and eventually burst due to extreme high water conditions. This deformation should be measurable with repeat pass SAR interferometry. An experiment with the PHARUS SAR was carried out to verify this. Two flights were carried out with 5.5 days in between them. During the data acquisition on the second day the dike was deliberately deformed. Interferogram analyses showed that the dike deformed by at most 2 mm on this day, in approximate agreement with tachymeter measurements. Unfortunately, the coherence of the interferograms formed by the data of the separate days was too low to measure deformation
