Analysis of Railway Subgrade Settlement Deformation in Permafrost Regions Based on Satellite Interferometry
SAR differential interferometry is an innovative space-based measurement technology for ground deformation. Under inclement Qinghai-Tibet plateau environment, monitoring and analysis of railway subgrade deformation using satellite interferometry in plateau permafrost region has very important engine...
