This paper is aimed at studying the temporal evolution of surface displacements occurred over past few years in ocean-reclaimed platforms Shanghai megacity (China), which are mainly ascribable to consolidation processes large dredger fills and alluvial deposits. With respect previous analyses carried out same area, this work provides a joint multi-platform differential interferometry synthetic aperture radar (DInSAR) analysis, based on application advanced Small BAseline Subset (SBAS) algorithm. led us retrieve long-term deformation time-series that helpful for better understanding on-going phenomena. To aim, we have exploited two sequences SAR data collected by ASAR/ENVISAT COSMO-SkyMed (CSK) sensors, respectively, spanning whole time period from 2007 2016. Unfortunately, gap (of about three years) existing between available CSK datasets gave rise additional difficulties their combination. Nevertheless, problem has been faced benefiting knowledge time-dependent model describing expected deformations affecting platforms.
