Abstract:According to the wide range of surface deformation, seventeen descending Sentinel-1A images are used to obtain subsidence information of Fushun from 2015 to 2016, based on the short baseline subset InSAR technique. The surface uneven deformation is analyzed using the information entropy method, and then the profile results of the typical regions in the east-west and south-north directions are extracted. Finally, the reliability of the experimental results is verified with existing. The results show that: 1) From June 2015 to June 2016, the deformation centers are distributed in the Fushun east open-pit mine, Fushun west open-pit mine, Tayu, Nanhuayuan, Xintun, etc. 2) The deformation information entropy of both Yulin and Zhanqian street is greater than 1.0, and the surface deformation is severely uneven, which should be monitored continually in the future. 3) The maximum subsidence is about 78 mm in the north side of the Fushun west open-pit mine; four subsidence funnels formed from west to east in the Fushun east open-pit mine, and the maximum subsidence is around 250 mm; the maximum value of the north subsidence region is 55 mm in Tayu township.
