 The study proposes an adaptable methodology for preventive monitoring of architectural heritage, using differential SAR tomography, Dtomo SAR, and a finite element method, FEM. The anchor watt temple was selected as the investigation target, and Dtomo SAR was used to calculate deformation, height, and thermal dilation. In SAR deformation measurements were used as constraints for 3D deformation simulation and structural monitoring. The results show that the integration of in SAR measurements prevented underestimation of structural instabilities, and linked physical models and mechanical parameters to FEM simulations. The anchor watt temple was found stable but with an absolute deformation rate of up to 3 mm per year, due to daily changes in thermal-related deformations caused by solar radiation. The study reveals the defect mechanism of the anchor watt temple and demonstrates the potential of the proposed method for health diagnosis, and preventive safeguarding of architectural heritage worldwide.
