The given paper considers the use of satellite radar interferometry techniques for the detection of ground surface deformations and technogenic objects displacements over a wide area. The relevance of the work consists of the need for identification of high geodynamical risk areas as a result of natural and anthropogenic factors. The main results of the work are the system of Sentinel-1A/B radar data full interferometric processing, geo-informational service for the publication of the processing results and interactive displacements map of Kaliningrad region for 2017-2018. The central part of the realized system is the previously developed and registered software FInSAR for radar data processing using persistent scatterers method. An important element of the system is geoportal which provides a user with access to the results and contains instruments for geospatial analysis. The interactive map of the Kaliningrad region represents point measurements of average annual displacements rate of technogenic objects with a possibility to trace displacements history. The paper consists of an introduction, two main sectionsand conclusions. The introduction is devoted to the actuality and practical significance of the developed system. The second section describes the characteristics of Sentinel-1A/B source data, radar interferometry technique and the persistents catterers approach. The third section describes the principal scheme of the system operation and the results of its use for technogenic objects displacements monitoring in the Kaliningrad region as an example. In the last section, the main conclusions are made and further direction of research and development in frame of the presented project is designated.
