GPS-InSAR合成方法进行地面沉降研究与展望

Prospect of InSAR-GPS Integration of Research into Land Subsidence

近年来 ,合成孔径雷达干涉测量 (In SAR)技术应用于地面沉降研究领域的方法与实例已在国内外工程实践和科研活动中多见报道。与此同时 ,利用 GPS技术监测地面沉降也日臻成熟与完善。GPS- In SAR合成方法作为二种方法的结合 ,能够在空间域和时间域同时提升地面沉降监测的能力 ,已开始成为国内外地面沉降测量技术研究的重点。本文综述了 GPS-In SAR合成技术的理论与方法 ,对其目前进展及应用前景进行了探讨。

More and more examples of Interferometric Synthetic Aperture Radar (InSAR) applied in the area of land subsidence have been reported recently at home and abroad. Meanwhile, application of GPS to measure land deformation has become an efficiently and accurately measuring technology. GPS-InSAR Integration can enhance the ability of measuring land deformation in both temporal and spatial resolution; it is becoming an emphasis of land subsidence investigation .This paper demonstrates the theory and method of GPS-InSAR Integration , and discusses of the prospect of GPS-InSAR.
