A Fast Connection Method for Disconnected Coherent Points in Time-Series InSAR Processing (opens in new tab)

Time-series interferometric synthetic aperture radar (TS-InSAR) has been extensively applied to ground deformation monitoring and disaster risk assessment. In this process, coherent point (CP) selection and connection are two essential steps. Typically, CPs are initially connected using methods such as Delaunay triangulation, followed by the estimation of deformation parameters for each edge. However, the removal of low-quality edges often fragments the initial network into multiple subnetwor...
