三峡库区滑坡灾害严重,应用传统监测方法不仅耗资巨大,而且效率不高。通过对近年来迅速发展起来的地表形变探测新技术——重轨星载InSAR技术进行了相关研究,并针对三峡库区近地表大气水汽含量变化频繁的特点,研究了大气水汽变化对重轨星载InSAR观测精度的影响,在对Zebker的相关研究结论进行实证后,探讨了重轨星载InSAR技术应用于三峡库区滑坡监测的可行性。 The landslide disaster in the Three Gorges reservoir area is serious. The application of traditional monitoring methods is not only costly but also inefficient. In this paper, the rapid development of surface deformation in recent years, a new technology - heavy rail onboard InSAR technology carried out related research, and for the Three Gorges reservoir near the surface of the atmospheric water vapor content of frequent changes in the study of atmospheric water vapor on the heavy rail satellite InSAR observation accuracy of the impact of Zebker in the relevant conclusions of the empirical study to explore the feasibility of using heavy-rail satellite InSAR technology applied to landslide monitoring in the Three Gorges reservoir area.
