Investigation on Volume Scattering for Vegetation Parameter Estimation of Polarimetric SAR Interferometry

摘要：

The objective of this paper is to investigate the volume scattering for the vegetation parameter estimation of Polarimetric Interferometric Synthetic Aperture Radar (Pol-InSAR). Firstly the models for describing the volume scattering are derived from the Pol-InSAR imaging geometry and volume scattering characteristics. The interferometric properties of volume scattering as well as the polarimetric properties of volume scattering are analyzed based on the model. Then the effects of volume height, extinction coefficient, ground to volume ratio, ground phase, incidence angle, and perpendicular baseline, on the volume scattering coherence are analyzed based on the Random Volume over Ground model. Furthermore, with simulated Pol-InSAR data, the effects of these parameters on the estimation accuracy of vegetation height are presented and the radar parameters for better estimating vegetation height are discussed.
