Outline
Addressing the challenges of weak scattering and low coherence in airport environments, we establishe a "macro-to-fine" hierarchical deformation monitoring framework based on the Chinese domestic "Fucheng-1" high-resolution SAR satellite, integrating SBAS-InSAR and an improved IPTA technique. A dynamic noise suppression baseline is constructed to optimize the amplitude dispersion index model, and an enhanced IPTA algorithm incorporating adaptive adjustment parameters is proposed, effectively mitigating the difficulty of coherent point selection in low-scattering areas. The results demonstrate that: 1) The improved algorithm increases the density of effective monitoring points within the airport area by 31.7% compared to conventional methods, with an internal accuracy better than 4.1 mm/a. 2) By incorporating multi-source environmental and meteorological data, the physical mechanism of minor differential settlement along the 1.5 km to 2.0 km runway segment is revealed to be driven by seasonal freeze-thaw cycles. The findings confirm the superior applicability and robustness of domestic high-resolution commercial SAR satellites combined with advanced time-series InSAR algorithms for monitoring subtle deformation in transportation infrastructure.
