The determination of crust movements by PS-Insar: Bolvadin case

In recent years, interferometric synthetic aperture radar technique has been used as a new tool for investigating deformation that occurs in earth surface. This technique which brings an original direction for geodesy by producing high quality topography information uses delays of the return signals and transforms them into high resolution images by signal processing techniques. At the same time, unlike other methods, this technique provides a wide workspace and provides with a sensitivity of centimeters. Thus Earth science researchers use this technique in studies of surface skin and the other fields. In life of foregoing, investigating of time bound height changes which happen in the ground for Bolvadin Konya with InSAR method was aimed in this study. To implement this aim we used interferometric synthetic aperture radar technique for investigation of crust movements and for this purpose we used 17 images which was selected in TerraSAR-X radar images that include the period from July 2016 to July 2018. Although this interferograms involve delays of signal that result from low coherence and atmosphere, we ascertained that the changes of position observed reveal crust movements, which reach approximately 12.5 millimeters, in direction of radar view in a two years period.
