Persistent Scatterers for SAR Interferometry (PS-InSAR) tecnique allows monitoring the temporal evolution of a deformation phenomenon at millimeter level, via the generation of mean deformation velocity maps and displacement time series from a data set of acquired SAR images. However, the serious noises of multi-temporal SAR images make the selection of permanent scatters (PSs) difficult. In this...
Multispectral and synthetic aperture radar (SAR) image fusion is one of the most complex tasks to perform integration of multi-source remotely sensed imagery. Fusion of SAR and optical remote sensing image, with highly complementary characteristics, may contribute to a better understanding of the objects with the imaged scene and finally benefit to application such as precision farming/ agricultural...
Numerous image processing methods to suppress the speckle noise in synthetic aperture radar (SAR) have been proposed. There is always a tradeoff between smoothing out speckle and preserving the useful spatial information (i.e. edge, texture). This paper proposed a novel index by integrating the evaluation of both speckle and edge preservation to evaluate the balance of the aforementioned two criteria...
Decorrelation caused by temporal change and SAR imaging geometry prevents conventional SAR interferometry from monitoring land surface subsidence precisely. In addition, conventional methods donpsilat deal with phase delay which caused by atmosphere. It negatively influences the accuracy of differential synthetic aperture radar interferometry (D-InSAR) for small-scale deformation monitoring. In this...
