Abstract

Synthetic aperture radar (SAR) remote sensing has enormous applications in the fields of agricultural crop monitoring, forest biomass estimation, glacier monitoring, urban mapping, sea surface object detection, deformation mapping, and so forth. In each application, precise scattering characterization of the target is necessary for effective quantitative analysis. This chapter gives an overview of different concepts and techniques related to target characterization using SAR remote sensing. The chapter is organized so that the reader will be briefly able to go through the technical details of SAR acquisition and SAR image representation and interpretation. The chapter concludes with a detailed mathematical explanation of an advanced decomposition technique called the polarimetric SAR interferometry decorrelation-based decomposition model for the scattering characterization of man-made and natural features.
