摘要: 利用CR-InSAR技术对鲜水河断层形变进行了研究。通过GAMMA软件对研究区获取的6幅安装角反射器(CR)后的ASAR数据进行处理,确定了道孚、七美和瓦日3个CR点在影像中的位置并提取它们的差分相位,在此基础上,建立了3个CR点观测模型并解算得到了它们的形变量。与实测的水准测量结果进行比较,结果表明,CR点形变监测结果与水准监测结果基本一致。Abstract: We study the deformation of Xianshuihe Fault using CR-InSAR.Firstly,we process 6 ASAR data,which were achieved after the corner reflector(CR) installation by GAMMA software.Then we get 3 CR points(Daofu,Qimei and Wari) position and CR differential phase in the images.Finally,the observation model for CR points is established to calculate the deformation value of CR points.The leveling results are compared.And the result show that the CR result is consistent with leveling result.
