一般注記Synthetic Aperture Radar Interferometry (InSAR) has been widely used to detect and monitor surface displacements induced by earthquakes, volcanoes, anthropic activities, etc. However, it is often suffer from spatial and temporal decorrelation. This paper provides some case studies carried out by the L-band PALSAR, which has offered an opportunity to conquer these limitations. More specifically, we present a new model to better consider the relationship between elevation and zenith wet delay, which is promising to mitigate atmospheric effects on PALSAR interferograms, and a new filtering model to improve the quality of interferograms. We then use two pairs of PALSAR interferograms and one pair of ASAR interferogram to monitor and evaluate the ground fissures in Xi'an, and we insert a set of PALSAR interferograms via the SBAS technique to retrieve displacement time series of Leizhou Peninsula, China. We also monitor the Yushu earthquake and Wenchuan earthquake using PALSAR data. More over, we infer 3D ground deformation due to L'Aquila earthquake, Italy with multi-platform SAR data. The result is consistent with GPS measurements. Through these work, we can better understand and utilize the PALSAR data on one hand and advance of InSAR technology on the other.
