摘要
合成孔径雷达干涉测量技术(InSAR)应用于地面形变监测已经成为地质灾害研究热点。本文分析了In-SAR技术在滑坡变形监测中的特点与技术优势,监测中InSAR、GPS的结合能够同时提高监测在空间域与时间域的分辨率;本文叙述了GPS、InSAR结合技术的理论与方法。说明利用干涉雷达结合GPS技术对滑坡进行监测是可行的,具有十分广阔的应用前景。
The powerful tool of Interferometric Synthetic Aperture Radar(InSAR)is drawing more and more attention in the field of landslide studies.The paper presents the characteristics and advantages of InSAR in landslide monitoring.The integration of InSAR and GPS in investigation of landslide can simultaneously improve both temporal resolution and spatial resolution.And it has become an effective way to investigate and manage landslide hazards.This paper demonstrates the theory and method of GPS-InSAR integration,and discusses its broad prospects in landslide monitoring.
