Abstract
This paper introduces the application of a new technique named Interferometric Point Target Analysis (IPTA) to monitor the land subsidence of urban areas in Suzhou city. It focuses on some points with high coherence to process. It uses a large number of SAR data set to analysis the spatial and temporal characteristics of some interferometric point targets. Firstly, it introduces the phase model of IPTA. Then it emphasizes on three aspects: the problem of selecting the master image; the problem of choosing the interferometric point target candidates; the data processing methods of IPTA technique. Then it can accurately get the history of land subsidence and atmospheric delay phase information.
