摘要:Stereo radargrammetry is a mature technique for deriving height information from SAR image pairs. Because stereo radargrammet ry is less sensible to temporal decorrelation, it can provide better results than interferometric SAR in certain s ituations. Using TerraSAR-X stripmap stereo pairs, digital surface models (DSM) with good height accuracy can be generated. We use SRTM data as our initial DEM and a pyramid layer based approach for our radargrammetric processing. Our results are relative noisy with a high error standard deviation. Nevertheless, with a mean overall error of less than 3 m in height the final DSM is quite precise
