Improved DInSAR time-series reconstruction in the presence of phase unwrapping errors using Huber-norm
IET Radar, Sonar & Navigation(2019)
摘要
Time-series reconstruction in differential interferometric synthetic aperture radar (DInSAR) requires solving a regression problem and can be used to monitor surface deformation. In this study, the authors present an improved time-series reconstruction for DInSAR using Huber-norm minimisation. The Huber-norm combines l2-norm and l1-norm based on a threshold retaining features of both norms. Unlike...
