应用INSAR进行黄河三角洲地面沉降监测研究

Research on Land Subsidence of Yellow River Delta With INSAR

在分析黄河三角洲的地面沉降状况及其对国民经济造成的影响的基础上,说明了对黄河三角洲进行地面沉降研究的必要性。综述了合成孔径雷达干涉测量的基本原理,针对近年来国内外干涉合成孔径雷达(INSAR)技术在地面沉降方面的研究和应用成果,分析了合成孔径雷达干涉测量技术应用于黄河三角洲地面沉降研究的可行性。

On the basis of land subsidence analyzing in Yellow River delta and the influence upon national economy, necessity of researching on Yellow River delta subsidence field is introduced. In this paper, the basic theory of interfemmetric synthetic aperture radar （INSAR） is summarized. With the recent research on INSAR and application in subsidence field, the feasibility of applying INSAR in the research of Yellow River delta subsidence is analyzed.
