In this study, deformations in the Line of Sight (LOS) direction were determined by using Permanent Scattered Interferometric Synthetic Aperture Radar (PSInSAR) method in the Kangal Coal Open Mine (Sivas-Turkey) region located in the southern part of Kangal district. German Space Agency's TERRASAR-X HighResolution Spotlight satellite radar images and European Space Agency's SENTINEL-1A Stripmap satellite radar images were used to detect movements in the LOS direction.
The main differences between Sentinel-1 and TerraSAR-X satellites are; We can list TerraSAR-X satellite data as ordering (SAR mode, coverage area, etc.), high resolution, high gain, and precise orbit information. However, the Sentinel-1 satellite is still in an advantageous position with its short transit times (6 days when Sentinel-1A and Sentinel 1B satellites are evaluated together) and regular repeat transitions in large areas (Gisinger et al., 2021). Generally; Monitoring of low roughness areas where detailed surface information is required, examination of deformations, landslides, and landslides
caused by infrastructure (building, road, dam construction) activities in residential areas, monitoring of ports and ships, monitoring of floods, water regime and agricultural activities in wetlands with short wavelength It is done via satellites using X band. In larger areas; In the monitoring of landslides, volcanic events, glacial movements, earthquakes, and deformations between earthquakes, satellites using C and L bands with long wavelengths are preferred (Bischoff vd., 2017; Vellotto vd., 2016; Meyer, 2021; Wang vd., 2021).
