DORIS软件应用于D-InSAR技术的研究
首发时间:2008-06-08
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。本文利用DORIS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DORIS软件进行的D-InSAR处理可以获得mm级的形变量。

STUDY ON DORIS SOFTWARE APPLIED TO D-INSAR TECHNOLOGY
Abstract:Geology disaster, such as Earthquake, volcano, coast and ground settlement, threaten the human more and more badly, 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 gain a deformation with the precision of millimeter level can be gained with the help of DORIS software.
Keywords: Ground deformation;DORIS software;D-InSAR technology;Bam ancient city
