【摘要】 地震、火山、滑坡和地面沉降等地质灾害越来越严重地威胁着人类,地面变形监测和测量显得尤为重要。D-InSAR技术是新近发展起来的一种极具应用潜力的地表形变监测手段。利用DOR IS软件对Bam古城震后的形变量进行提取。结果表明,在研究区相干性较好的前提下,借助于DOR IS软件进行的D-InSAR处理可以获得mm级的形变量。更多还原

【Abstract】 Geology disasters,such as earthquake,volcano,coast and ground settlement,threaten the human more and more seriously,Therefore,it is of particular importance to monitor and measure ground deformation.D-InSAR technology is a powerful method to monitor the ground deformation.The paper extracts deformation of Bam ancient city after earthquake by DORIS software.The result shows that D-InSAR technology can obtain a deformation with the precision of millimeter level with the help of DORIS software.更多还原
