摘要：
InSAR Processing and especially phase unwrapping is a crucial step in the realization of the global TanDEM-X DEM. After three years of operation, the InSAR chain has delivered more than 350,000 RawDEMs, which mostly fulfill already the high accuracy requirements. At the same time, it has been also optimized and improved to cope with input data of various quality. Special efforts have been made in the dual-baseline interferometric chain to deal with CoSSCs with larger ranges of height of ambiguity and time spans. This paper presents the key elements of the InSAR chain and analyses the dual-baseline phase unwrapping results.
