摘要

为推进合成孔径雷达差分干涉测量(D-InSAR,Differential Interferometric Synthetic Aperture Radar)技术在地表沉降地理国情监测中的应用,本文利用D-InSAR技术,以某矿区为研究对象,基于5景哨兵-1卫星(Sentinel-1)雷达影像,采用SARscape与Arc GIS软件相结合处理的方式得到了精准的成果数据,并结合实地水准观测结果对D-InSAR地表沉降监测的精度进行了对比分析。结果表明:利用D-InSAR技术进行地表沉降地理国情监测,具有较高的测量精度,且该技术具有大尺度连续覆盖能力、受天气干扰小、低成本等特点,在地理国情监测等相关领域有非常好的应用前景。
        In order to promote the application of D-In SAR( Differential Interferometric Synthetic Aperture Radar) technology in national geoinformation settlement monitoring,a study in a mining area based on D-In SAR and Sentinel-1,in combination with SARscape and Arc GIS software was performed,which was proved to be a great success in obtaining accurate date. Meanwhile,the precision of national geoinformation settlement monitoring using D-In SAR technology was compared with field level observation. The results show that the application of D-In SAR has good prospect in national geoinformation settlement monitoring because of its high precision,large scale continuous coverage,small weather interference and low cost.
