We exploit the Extended Minimum Cost Flow (EMCF) Phase Unwrapping (PhU) technique that allows us to process sequences of differential SAR interferograms in order to generate deformation time-series. We discuss first the basic rationale of the EMCF approach, highlighting its capability to process both multi-look and single-look interferogram sequences. Subsequently, we demonstrate the algorithm effectiveness by presenting the results obtained processing ERS SAR data relevant to the city of Rome, Italy.
