应用重轨星载InSAR技术监测三峡库区滑坡形变探讨

Monitoring Landslides Deformation in Three Gorges Reservoir Area by Using the Repeat-pass Spaceborne InSAR

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。

Three Gorges reservoir region＇s landslides calamities are serious,using traditional monitoring methods monitor landslides which are inefficient and cost enormously.This paper study new deformation monitoring method-the repeat-pass spaceborne SAR interferometry developed rapidly on the recent years.based on the characteristics of atmospheric water vapor near surface vary frequently,this paper analyses atmospheric water vapour effects on the repeat-pass spaceborne SAR interferometry.After demonstrating Zebker＇s correlated conclusions,discuss the feasibility of monitoring Three Gorges reservoir region＇s landslides by using repeat-pass spaceborne SAR interferometry.
