Description: Seasonal freezing and thawing cause surface deformation is the main disease permafrost area construction projects, permafrost heave and thaw settlement is an important factor in the current construction of the Qinghai-Tibet Highway and Qinghai-Tibet railway embankment stabilizing influence in recent years, the differential interferometry techniques have been surface deformation become an important tool for measuring and monitoring. Repeat track ERS-1/2 radar image based on research using SAR interferometry technique to detect permafrost deformation method, after the introduction DEM differential interferometric SAR technology processing and analysis, research permafrost deformation results by comparison with the measured data, indicate heavy rail differential interferometry can accurately detect permafrost surface deformation, can be used for deformation monitoring permafrost.
