ABSTRACT Traditional surface monitoring methods can only obtain discrete deformation values at individual points, while InSAR technology measure the projection of three‐dimensional along LOS direction. Additionally, when in mining areas, it may encounter issues low coherence or even loss coherence. Therefore, this paper proposes a method for predicting filling based on InSAR‐IPIM. The results show that proposed effectively corrects error caused by use empirical parameters to predict NC1202. deviation rates between optimal and initial are 23.61%, 34.29%, 16.32%, 0%, 14%, 3.85%, 4%, 7.4%, respectively. predicted complete subsidence area results. Compared with maximum measured leveling data, absolute vertical field is 1 cm, which small, making possible working face using single track SAR data.
