摘要: 在机场填海区地表稳定散射的范围内,本文运用合成孔径雷达干涉测量(InSAR)技术对机场地表形变安全性进行了监测分析,反演获得了研究区域范围内的年形变速率数据结果和高分辨率形变时序结果,并以此分析了香港国际机场的地表形变区在监测周期内的形变时空分布特征。为证明监测结果的精度和可靠性,本文采用全球导航卫星系统(GNSS)观测站的垂直位移数据,对InSAR方法反演的结果进行了交叉验证,证明两者具有良好的一致性。

Abstract: In order to monitor the safety of the airport surface deformation, the synthetic aperture radar interferometry (InSAR) technology is used to monitor and analyze the stable scattering of the airport reclamation area. The annual deformation rate data results and high-resolution deformation time series results in the study area are obtained by inversion, and the temporal and spatial distribution characteristics of surface deformation in the monitoring period Hong Kong international airport are analyzed. In order to prove the accuracy and reliability of the monitoring results, the vertical displacement data of GNSS (global navigation satellite system) observation station is used to cross verify the inversion results of InSAR method, which proves that the two methods have good consistency.

Key words: synthetic aperture radar interferometry, deformation, time series, spatial and temporal distribution characteristics, accuracy verification
