ABSTRACT
The article shows the results of research for detecting of vertical shifts of the earth’s surface based on data obtained from radar images of COSMO-SkyMed and TerraSARX satellites with the usage of the differential interferometry method. A displacement map of the earth’s surface of a test site and mining area of approximately 900 square kilometers is presented. It is shown that the results of calculations using differential interferometry are consistent with the results of ground-based topographic and geodetic measurements and provide accuracy to within one centimeter. Satellite radar interferometry is a method of remote sensing technology, providing high accuracy of the heights and offsets by using the phase components of the signal.

Keywords: satellite radar images, differential interferometry, earth surface displacement
