Evaluation of the Sentinel-1A radar interferometry accuracy applied in mining areas

Abstract

The two-year period of the latest satellite mission of the European Space Agency provided images that support analysis of ground vertical displacement on the mining areas. Satellite Sentinel-1A gives the possibility of carrying out such investigation in the cycle of 12 days. In the article the comprehensive introduction to the technological aspects of the processing of satellite images has been presented. The essential research was concentrated on the analysis of periodic vertical movement of the terrain surface located above underground mining operation from 2015 to 2016 . The SAR images processing was provided based on DInSAR method. The research confirmed relative high accuracy of vertical points movement observed based on SAR images in comparison with the classical leveling. Not only the high effectives of presented method has been proved, but also limitation of that solution has been discussed. The authors summarize their achievement giving directions for future research in this area.
