Abstract

In synthetic aperture radar interferometry, permanent scatterers (PSs) can be regarded as a series of measurement points which is not or less influenced by temporal and geometrical decorrelation and atmospheric delay. How to effectively detect and identify PS from SAR images is one of the crucial procedures in PS interferometric system. In this paper, we present a complete procedure for the identification and exploitation of stable natural reflectors or permanent scatterers (PSs) starting from long temporal series of interferometric SAR images based on ICA. Using 4 SAR images at different time over Nanjing from satellites ENVISAT of European Space Agency, some experiments are then carried out to evaluate the performance of the proposed method both visually and quantitatively.
