摘　　要：雷达干涉测量技术为地面沉降高精度快速准确监测提供了新的手段。对于数万平方千米的大范围地面沉降,要求测量手段不仅具备高精度,还要具备大范围同步测量的能力。为解决这一问题,本文提出了利用Sentinel-1数据结合SBAS技术的监测方法,首先对黄河三角洲区域进行形变监测,然后利用CORS数据进行验证,最后对地面沉降的时空分布情况进行分析。该研究证明了采用该方法对大区域形变监测的适用性,为该区域沉降预防和治理提供了重要依据。Radar Interferometry technology provides a new method for high-precision,rapid and accurate monitoring of ground subsidence. However,when the ground subsidence covers an area equal to tens of thousands of square kilometers,high measurement accuracy and large-range synchronous measurement is required. In order to solve this problem,Sentinel-1 data are used to analyze terrain deformation in the area of Yellow River delta,the CORS data is used for verification and temporal and spatial distribution of land subsidence is examined. The study demonstrates the applicability of this method to deformation monitoring in large area,and provides an important basis for subsidence prevention and control in the region.
