Abstract
SAR satellite technology is increasingly used tool for the study of natural hazards present on the surface of the Earth. Interferometric SAR (InSAR) and Differential Interferometric SAR (DInSAR) methods are basic tools for such analysis. InSAR method is mainly used in Digital Elevation Model (DEM) estimation. In DInSAR method phase difference between satellite images is computed. Phase difference indicates occurrence of ground deformations. In both cases the final product should be presented in unwrapped interferogram form. Unwrapped interferogram contains numerical values of estimated DEM or subsidence values. Due to a long time and incorrect results possibilities this step is often ignored. The main problem of this method is the presence of noise in the radar images. Speckle noise is an integral part of the interferometic image. The way to avoid speckle problem is to use mask on incoherent parts of interferogram. In the presented paper Goldstein interferogram filtering method was used to reduce noise in coherent areas. Second part of analysis uses mask on incoherent areas based on coherence analysis results between satellite images.
