Polarimetric SAR interferometry for forest application at P-band: Potentials and challenges

This paper presents the impact of simulation parameters according to the potential future space-borne mission BIOMASS (P-band) in polarimetric and interferometric SAR (Pol-InSAR) inverison performance. Forest height inversion is obtained from the simulated data sets (bandwidth, NESZ and ambiguities) generated from DLR E-SAR (Experimental Synthetic Aperture Radar) airborne SAR data. For this study two campaign data sets (BioSAR 2007 / INDREX-II) have been selected and investigated. The several comparative results of Pol-InSAR between airborne data and the simulated data (incl. bandwidth, NESZ and range/azimuth ambiguities) will be shown and discussed.
