Abstract	With a spatial resolution of up to 1 m, the German radar satellite TerraSAR-X has significantly improved the applicability of spaceborne SAR interferometry (InSAR) technique for fast ground motion monitoring due to its high spatial resolution and short time interval. In this work we present the first Permanent Scatterer Interferometry analysis with TerraSAR-X data for urban subsidence mapping in Tianjin city in China. Totally 17 scenes strip mode SAR images have been collected from Feb to Oct 2009 to perform the PSI analysis. The resulted average subsidence velocity demonstrates the ability of high resolution data for detailed monitoring of urban subsidence. Comparison between PSI result of TerraSAR-X and ENVISAT show the potential of TerraSAR-X data for urban motion as well as large scale manmade linear infrastructure monitoring.
