InSAR Analysis Ready Data

The Sentinel-1 satellite constellation provides temporally dense and high spatial resolution Synthetic Aperture Radar (SAR) imagery. The open data policy and global coverage of Sentinel-1 enables applications that require long time series, such as modelling surface deformation rates from Interferometric Synthetic Aperture Radar (InSAR) data, to be scaled-up and generate continent-scale products. In this paper, we present a workflow to generate interferometric products from the Copernicus Australasia Regional Data Hub archive of Single Look Complex (SLC) Sentinel-1 data, with the objective to derive a continent-wide ground surface deformation map for Australia. The proposed workflow can be used to generate Sentinel-1 InSAR Analysis Ready Data (ARD) suitable for ongoing monitoring of ground deformation.
