Abstract: Classical methods to observe deformations of the Earth's surface are currently labour-intensive and time-consuming, and not safe in some cases. In the paper reviews the radar interferometry method to study deformations of the Earth's surface, which is a supplementary technique for traditional methods. Remote sensing data is used as the input information for the calculations used in this method. Two approaches are used for interferometric data analysis: the area-based interferometric analysis, which allows to build interferograms of the whole area, and the point-based analysis of permanent deflectors, which is used to create historical maps of the Earth's surface displacement. Despite the high development level of remote sensing methods, the radar interferometry technique, which allows to measure small angular details with radio-frequency emissions from the sky, can not be used as an independent method to determine the subsidence of the earth's surface due to the relatively little studies of how the external factors impact the measurement accuracy.

Keywords: radar interferometry, interferograms, deformations, displacement of the earth's surface, methods of remote sensing of the earth, space vehicles
