Go Extra Miles: An Additional Error Correction Procedure Aimed to Further Improve Phase Unwrapping Accuracy and Reduce Creep Model Uncertainty

Abstract: Interferometric Synthetic Aperture Radar (InSAR) phase unwrapping error is a major limiting factor on the InSAR‐derived tectonic deformation velocity. This is particularly the case when atmospheric turbulence, large deformation gradient and strong phase noise exist. To address limitations of existing phase unwrapping error correction methods, here we present a new algorithm that integrates decorrelation phase correction, triplet phase closure (TPC) test and integer linear programming (ILP) to overcome this lim… Show more

“…The authors would like to thank the editors and three anonymous reviewers for their help and valuable comments. We are also very grateful to an anonymous reviewer for his valuable comments on azimuth misregistration error correction during the review process of [55], which led us to begin paying attention to the influence of plate motion on misregistration. We thank Global Centroid Moment Tensor Catalog (GCMT) for providing earthquake catalogs (https://www.globalcmt.org/).…”

“…Its novelty and behind rationale are to decompose 2D deformations of each event through fusing multi-track and multi-temporal interferograms. In the decomposition, MTMT2D include two significant steps: CSPUEC (Compressed Sensing based Phase Unwrapping Error Correction) method [18] and SIGMA ( Strain-model based InSAR for Geo-hazards' Monitoring Approach) [19].…”
