Description
Summary:The goal of this work is the generation of an X-Band backscatter map by assembling images acquired by the TerraSAR-X mission. Global backscatter data is required for accurate performance estimation and instrument commanding inside the TerraSAR-X and TanDEM-X missions. Moreover, many scientific applications can be based on the analysis of backscatter behavior and evolution. The complete ground coverage will be achievable with TanDEM-X mission data. An interpolator, that allows the estimation of the backscatter for any required polarization and incidence angle from the available data, has been implemented. In this paper, the backscatter map generation algorithm will be presented, together with the first obtained results, generated using TerraSAR-X data. Moreover, the validity of the interpolation models will also be discussed, presenting the preliminary results of a statistical analysis of backscatter from TerraSAR-X data.
