Abstract
Deformations in mining areas have been started to be monitored by satellite SAR-based methods, which have recently emerged as an alternative to classical methods (GNSS receivers, Geometric Leveling, Terrestrial Lidar, UAV Photogrammetry, etc.). The most important advantage of this method is that quite wide areas can be monitored remotely. However, the mentioned way also has some disadvantages. The first of these; deformations can only be determined in the direction of the Satellite Line Of Sight (LOS), and the second one is that there is no correlated reflective surface due to the continuous change of topography in the locations where mining activities are carried out. Within the framework of this study, it is aimed to monitor PS by placing corner reflectors (CR) in the locations where sufficient Permanent Scatterer (PS) cannot be produced in Kalburçayırı and Hamal Coal Fields of Kangal Thermal Reactor Elektric production A.Ş. By considering the area through Sentinel-1A/B satellites, new PSs constituted by employing the CR facility has been successfully observed in locations, where PS could not be produced before. The results show us that; placing corner reflectors in locations where sufficient PS cannot be made or not determined at all, increases the number and quality of PS positively.
