摘要: Processing of interferometric ERS SAR data is still a challenging task. The amount to be handled enormous, the input often expensive, quality priori unknown, algorithms require fast computers and some key like phase unwrapping are under development. Therefore, investigating large scale tandem not straightforward In an attempt assess with respect DEM generation prepare for operational processing SRTM (Shuttle Radar Topographic Mission, [3]) digital elevation models (DEMs), DLR processed more than 700 interferograms into base. This paper describes systems involved, notes products generated. From our experience, can now done in automatic manner, but deriving DEMs difficult task operator interactions required.
