摘要：
Stable natural reflectors (Permanent Scatterers) can be identified from long temporal series of interferometric SAR images even with baselines larger than the decorrelation one. We discuss the use of PS in urban areas, like Pomona (California) showing subsidence and absidence effects. An estimation of the Atmospheric Phase Screen (APS) superimposed on each image and the displacement field in the area of interest is carried out. New solutions are presented in order to cope with non-linear motion of the targets.
