CR-InSAR与PS-InSAR联合解算方法及在西秦岭断裂中段缓慢变形研究中的应用
|
摘要
本文结合CR-InSAR、PS-InSAR技术,将CR、PS点联合构网,采用LAMBDA方法进行相位解缠,研究西秦岭北缘断裂带中断的微小形变,结果得出断裂带表现出左旋走滑运动特征,断裂带南盘平均形变速率为2.3mm·a~(-1),北盘平均形变速率为-1.5mm·a~(-1),南北两盘平均形变速率差异为3.8mm·a~(-1),与其他学者GPS、地质测年研究成果相近.对研究区内的角反射器(CR点)安装、影像特征分析及形变解算进行了较为详细的论述,并对比分析了CR、PS点联合构网和PS点单独构网解算结果,得出对地质环境复杂的断裂带做永久散射体形变研究时,CR、PS点联合构网解算结果好、研究结果可靠.说明CR、PS点联合构网中,CR点由于其自身的高稳定特性,对整个解算网络起到了很好的整体控制作用,保证了解算结果正确.
In this work,the combination of CR-InSAR and PS-InSAR technique is used to measure the trival deformation on the middle section of the West Qinling north edge fault by constructing CR\PS network jointly,in which the phase is unwrapped by using the LAMBDA method.The result shows left-lateral strike-slip movement on this fault.The average deformation rates of the northern and southern walls of the fault are-1.5mm·a~(-1) and 2.3mm·a~(-1),respectively.It means that the relative average deformation rate between two fault walls is approximately 3.8mm·a~(-1),which is consistent with results from GPS measurement and geologic dating.Meanwhile,this paper details the Corner Reflector(CR points)installation,its image features and deformation solving method.Comparing the results from the CR\PS-InSAR and PS-InSAR shows that the results achieved by joint inversion of CR\PS network is more reliable than that from using PS points alone in complex geological environments.The result indicates that CRs play an important role in entire network,ensuring a correct and reliable deformation measurement because of its high reflection stability.
