ITERATIVE MULTISTAGE POLARIMETRIC SCATTERING DECOMPOSITION OF RADARSAT-2 AND ALOS-2 PALSAR-2 DATA

Abstract

This paper examines our previously proposed gravitational filter and iterative multistage model-based polarimetric decomposition for an improved scattering retrieval from multi-look RADARSAT-2 C-band and ALOS-2 PALSAR-2 L-band data over a coastal region in the tropics. The decomposition results showed that a large amount of negative power pixels over vegetated areas were reduced. The retrieved scattering properties for different land cover types, namely, mangrove forest, oil palm, and rice paddy, were also analyzed and are discussed in this paper.
