Abstract :
A processing technique for polarimetric SAR data has been developed which produces profiles of terrain slope in the along-track (or azimuthal) direction. Using P-band data, slope profiles have been obtained for forest scattering conditions (biomass, soil moisture…) prevalent in the Black Forest near Freiburg, Germany. The radar-measured slope (and derived elevation) profiles have low RMS errors and high correlation values when compared with a digital-elevation map for the area. The algorithm has also been successfully tested in nearby non-forested regions, and is capable of adaptively transitioning across forest/field boundaries
