Abstract:In this paper, the Hongqinghe coal mine in Ordos city is taken as the experimental object, the interference processing and time series analysis of Sentinel-1A satellite image are carried out. By analyzing the similarity degree of the statistical attributes of time dimension samples, the pixels with the same scattering characteristics are selected for homogeneous filtering, and the phase is adjusted according to the phase closure principle in the complex field to realize the DS-InSAR processing in this area. The accumulated subsidence area of the coal mine is about 32.3 km2, and the subsidence results are consistent with the spatial distribution of the coal mine. Compared with the results of PS-InSAR, DS-InSAR has better effect in subsidence monitoring.
