Comparative analysis and scale effect of urban deformation monitoring using PSInSAR and SAR images with different resolutions
“Time series InSAR technology can monitor the deformation of urban buildings on a large scale with high accuracy. There have been many related studies and engineering applications. Based on low, medium, and high resolution SAR images of the same area and monitoring period, researchers used PSInSAR technology to verify that a decrease in SAR image resolution will lead to a weakening of the overall ability of fine monitoring of urban deformation, laying the foundation for the construction of urban building deformation monitoring system.”
