A Review of Time-Series Interferometric SAR Techniques: A Tutorial for Surface Deformation Analysis

Over the past two decades, the time-series interferometric synthetic aperture radar (InSAR) technique has been developed to estimate surface deformation parameters. Because of its ability to monitor large-scale deformation with millimeter accuracy, the time-series InSAR technique has been applied in many fields, such as urban infrastructure monitoring, mining subsidence, and landslides. The obtained, long-term, time-series cumulative deformation is of great value to the study of its regularity.
