In this paper a new method of dual-polarimetric SAR image coregistration procedures is proposed. Both cases - coarse and fine coregistration are considered. In the proposed approaches the widely used coherence parameter is not applied. Instead, the dual-polarimetric signatures are exploited. They allow to identify location of strong point scatterers within the SAR images. These scatterers can be further used in coregistration procedure as reference points. The developed algorithms described in this work were teste...

This work presents improvement of land subsidence monitoring obtained by combining results of Sentinel-1A and Sentinel-1B data processing. In presented work DInSAR (Differential Interferometry SAR) technique was used. Results of DInSAR technique provide information about values of vertical deformation of the surface. Using this technique the areas endangered by subsidence phenomenon can be identified and appropriate steps in order to save the infrastructure, buildings, roads, and also human life can be taken. The ...
