Polarimetric SAR pixel offset tracking for large-gradient landslide displacement mapping

Polarimetric SAR pixel offset tracking for large-gradient landslide displacement mapping

Interferometry and pixel offset tracking (POT) are two major technologies to measure ground deformation with repeat-pass synthetic aperture radar (SAR) observations. The SAR POT method can tolerate a much larger deformation gradient than interferometric SAR (InSAR), and thus it has been widely appli...
