Insar Error Budget for Large Scale Deformation

Abstract: The capacity of SAR interferometry to measure surface deformation with accuracy of 1 mm/year or better are well known. However this is typically limited to relative motion at short distance. Thanks to several advances in SAR sensor quality, data availability, orbit determination, processing, and calibration of atmospheric delays it is now possible to achieve that accuracy even across large distances of hundreds of kilometers. In this paper we revise the main contributions to the large scale error, considering … Show more

“…As revealed by the comparisons, both the bias and dispersion decrease when more interferograms are exploited for phase and, consequently, deformation estimation. The overall performance of the E-StBAS techniques is observed to be worse than the achievable precision of 1-2 mm/year for the Sentinel-1 data stacks [23], [24], while the exploitation of the full covariance matrix helps EMI in retaining this potential performance.…”
