Feasibility of ALOS2 PALSAR2 Offset-Based Phase Unwrapping of SAR Interferogram in Large and Complex Surface Deformations

The interferometric synthetic aperture radar (InSAR) is a well-known tool for mapping ground surface deformations with centimeter precision, and is much better than that used in the offset tracking method. However, the InSAR method has difficulties in precisely measuring large deformation signals be...
