Therefore, it is essential to monitor surface subsidence in mining areas. In recent years, PSInSAR technology has attracted attention as an efficient and accurate method for monitoring surface subsidence.This paper aims to study the selection method of permanent scatterers in surface subsidence monitoring in mining areas to improve the accuracy of surface subsidence monitoring.Firstly, the basic principle of PSInSAR technology is introduced, and its application in surface subsidence monitoring is briefly described. Then, the problem of selecting permanent scatterers in surface subsidence monitoring in mining areas is analyzed in detail, and a method based on grey correlation is proposed. Finally, the method is validated by 精品文档---下载后可任意编辑simulation experiments, and the experimental results are analyzed and discussed.Through the research of this paper, the accuracy and reliability of surface subsidence monitoring in mining areas can be effectively improved, providing powerful technical support for mining and ecological environment protection.【Keywords】PSInSAR technology; mining area; surface subsidence; permanent scatterers; grey correlation
