Proposed Method for Improving PSI Capabilities in Ground Deformation Monitoring for The Application of Geo-Energy Projects

Abstract. Persistent Scatterer Interferometry (PSI) is a powerful Synthetic Aperture Radar (SAR) technique capable of detecting millimeterscale deformation. However, the technique faces limitations related to the observed ground or areas and the phase unwrapping stage. This research proposes an integrated approach to address these limitations by combining multiple images from different sensors. The integrated method aims to provide more coverage and additional data to partially overcome the weaknesses of the PSI technique. The article introduces the proposed integrated approach and provides insights into the workflows required to apply this method on geoenergy projects.
