基于D-InSAR技术的煤矿区地面沉降监测研究

Monitoring of Land Subsidence in Coal Mining Area Based on D-InSAR Technology

概要叙述了差分合成孔径雷达(D-In SAR)的技术原理和数据处理方法,介绍了D-In SAR在地表形变监测中的应用技术和方法,针对研究区域的地表沉降特点选择常规D-In SAR和永久性散射体干涉测量(PSI)作为In SAR差分处理方式,分析并选取适合本项目研究的In SAR雷达数据,对兖州-济宁区域因煤矿开采产生的地表缓慢沉降和快速沉降进行数据分析并得出结论,达到了研究的目的。

This paper briefly described the principle and data processing methods of the Differential Interferometric SAR（D-InSAR）technology,and introduced the application techniques and methods of D-InSAR on monitoring of the ground surface deformation.According to the characteristics of the ground surface subsidence in study area,we choosed conventional D-InSAR and Permanent Scatterer Interferometry（PSI）as the InSAR differential treatment,and analyzed and selected the InSAR radar data that is suitable for the study.Finally,we have drawn some conclusions by analyzing data of both the slow and rapid ground surface subsidence caused by the coal mining in Yanzhou-Jining area,and have achieved the purpose of the research.
