CTM 기술이란 :
The ability to analyze multiple InSAR pairs facilitates the estimation
of subtle displacement in areas where existing deformation mapping
methodologies are hampered due to temporal de-correlation. A significant
challenge in traditional interferometric deformation mapping is
the de-correlation due to changes in ground cover and atmospheric
differences between observations. Some point-like targets. However,
do not de-correlate over time, making it possible to estimate deformation
at these locations. The goal of the CTM module is to extract deformation(derived
from phase information) from multi-temporal interferograms in areas
where "temporal coherence" exists. Analyzing the phase
information must properly account for errors due to atmospheric
and DEM errors. this new capability will facilitate monitoring and
assessment of potential damage to large structures such as buildings,
bridges, pipelines and reservoirs.
