InSAR Kalman Filter Phase Unwrapping Algorithm Based on SRTM DEM

Abstract

PU (phase unwrapping) is the key step and important problem in DEM (digital elevation model) extraction and the measurement of surface deformation of InSAR (Interferometric synthetic aperture radar). The CKFPUA (conventional Kalman filter phase unwrapping algorithm) can obtain reliable results in the flat terrain areas, but it caused error transmission not… (More)
