AbstractLarge-scale man-made linear features has played more and more important role in modern life and the development of urban are seriously affected by the subsidence of them. Permanent Scatterers (PS) technology was developed as a powerful tool for subsidence monitoring. High resolution of 1m data can be provided by TerraSAR X-band (TSX) with a short revisit period of 11 days. More detail and sensitive subsidence information can be expected to be detected by X-band. In this paper, we exploited the potential of TSX for railway subsidence monitoring. A case study was conducted in Tianjin. A total of 37 TSX images acquired from 2009/4/29 to 2010/11/11 were used in PS analysis. The average deformation map and geocoded Permanent Scatterer were generated by SARPROZ. © 2011 IEEE.
