Baseline Analysis of Polarimetric SAR Interferometry

摘要：

Polarimetric SAR Interferometry (Pol-InSAR) combines SAR interferometry (InSAR) and SAR polarimetry (PolSAR), and it helps to the generation of digital elevation models (DEMs) as well as the parameter estimation of natural volume scatters. Baseline is an important concept in conventional InSAR applications. With the introduction of polarization into InSAR, the baseline requirements of Pol-InSAR are different from those of InSAR. In this paper baseline decorrelation, which includes surface decorrelation and volume decorrelation, is firstly analyzed with the random volume over ground (RVoG) model. Then some different considerations in choosing baseline between Pol-InSAR and InSAR are presented. Finally methods of determining Pol-InSAR baseline are given and discussed.
