Monitoring of displacements and deformations of the earth’s surface near the Stebnyk city using radar images of Sentinel-1

This article applies radar interferometry technologies implemented in the ENVISARscape and SNAP software environment provided by the processing of data from theSentinel-1 satellite. The study was carried out based on six radar images of Sentinel-1A andSentinel -1B taken from September 2017 until February 2018 with an interval of one monthand on the radar-module of the already mentioned SNAP software. The main input data forsolving the considered problem are radar images received from the satellite Sentinel-1B onthe territory of Stebnyk-Truskavets for six months with an interval of one month. Monitor-ing of the Earth’s surface using radar data of the Sentinel-1A with a synthesized apertureis implemented with the application of interferometric methods of Persistent Scatterers andSmall baselines interferometry for estimating small displacements of the Earth’s surfaceand structures. The obtained quantitative and qualitative indicators of monitoring do notanswer the processes that take place and lead to vertical displacements the six months butdo provide an opportunity to assess the extent and trends of their development. The speci-fication in each case can be accomplished by ground methods, which greatly simplify thesearch for sites with critical parameters of vertical displacements which can have negativeconsequences and lead to an emergency.
