N2 - Many urban areas are experiencing land subsidence due to water, oil and natural gas withdrawal, underground construction, sediment compaction, and so on [1-3]. The X-band SAR system such as TerraSAR-X and Komsat-5 has higher spatial resolution than C-band and L-band system. Therefore it is valuable for effective monitoring of urban area in terms of detecting subtle surface deformation and reconstructing 3-D building structure. Here we present the time-series deformation from 20 TerraSAR-X SAR data over New Orleans, USA. The Gamma software was only used to extract sensor parameters from TSX's xml file, and modified ROI-PAC 2.2.2, which is optimized for high resolution SAR, was used for interferometric SAR processing. Both persistent scaterrer InSAR and SBAS technique were applied for analysis of time-series deformation. According to initial X-band InSAR result, high accuracy and spatially dense subsidence map was obtained by TerraSAR-X InSAR analysis. Deformation map derived from TSX will be compared with other satellite's results such as RADARSAT-1[1].
