Application of Dual-Polarimetry SAR Images in Multitemporal InSAR Processing [PDF]

open access: yes, 2017
Multitemporal polarimetric synthetic aperture radar (SAR) data can be used to estimate the dominant scattering mechanism of targets in a stack of SAR data and to improve the performance of SAR interferometric methods for deformation studies.
