Title
Uncertainty analysis in advanced differential interferometric SAR processing
Abstract
The DInSAR technique enables to determine with precision the surface displacements, using a combination of multiple interferograms. The DInSAR processing steps generate different kinds of errors, which propagate in the entire chain. This work is focused on a particular type of error generated during the DInSAR processing: the unwrapping related errors. The errors generated during the unwrapping process and the use of a procedure to automatically detect and correct them are presented in this work. By an iterative process and exploiting the SVD least squares method for outliers rejection, this procedure determines the phases values associated with each SAR image, starting from a stack of interferograms. It works on previously selected pixels and provides good results with high observation redundancy. The effectiveness of the procedure is illustrated by using ERS SAR data acquired over Barcelona (Spain).
