A phase-decomposition-based polarimetric coherence optimization method

International Journal of Applied Earth Observations and Geoinformation, 2022
The interference between different scattering components in distributed scatterer (DS) makes it difficult to estimate the phase from DS. Recently, some methods based on eigenvalue decomposition (EVD) are proposed to separate scatterer components from DS,

Quantification of Temporal Decorrelation Effects at L-Band for Polarimetric SAR Interferometry Applications

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2013
Temporal decorrelation is the most critical issue for the successful inversion of polarimetric SAR interferometry (Pol-InSAR) data acquired in an interferometric repeat-pass mode, typical for satellite or lower frequency airborne SAR systems.
