Dual-baseline phase unwrapping correction for the TanDEM-X mission: After one year experience

This paper presents the processing results of the dual-baseline phase unwrapping correction chain of the Integrated TanDEM-X Processor. Second year data are operationally processed since August 2012 with the help of supporting CoSSCs. They are shifted of half a swath width with respect to the first year data. Supporting CoSSCs are the first year scenes. The first and second year scenes have different height of ambiguity but are taken from the same look angle. The chain has to deal with huge amount of data of different quality and from every part of the world landmass. A success rate of more than 97% is achieved overall.
