This paper describes a Persistent Scatterer Interferometry procedure to process Sentinel-1 SAR data. Its most original part includes a set of tools to perform two key processing stages: a first 2 + 1D phase unwrapping, prior to atmospheric filtering, and a second 2 + 1D phase unwrapping, to generate the deformation time series. These tools address two fundamental aspects of a Persistent Scatterer Interferometry processing chain: the quality control of the intermediate and final results, and the generation of quality indices to characterise such results. The effectiveness of the proposed tools is illustrated using a case study located in Catalonia (Northern Iberian Peninsula)

Abstract
This paper describes a Persistent Scatterer Interferometry procedure to process Sentinel-1 SAR data. Its most original part includes a set of tools to perform two key processing stages: a first 2 + 1D phase unwrapping, prior to atmospheric filtering, and a second 2 + 1D phase unwrapping, to generate the deformation time series. These tools address two fundamental aspects of a Persistent Scatterer Interferometry processing chain: the quality control of the intermediate and final results, and the generation of quality indices to characterise such results. The effectiveness of the proposed tools is illustrated using a case study located in Catalonia (Northern Iberian Peninsula)File | Dimensione | Formato | |
