利用InSAR及其差分技术获取仲巴地震的同震形变场
|
摘要
本文简要介绍了InSAR及其差分技术的基本原理,并以仲巴地震为例,采用已知DEM的二路差分法获取了仲巴地震的同震形变场。结果表明:仲巴地震为是一个以倾滑为主的浅源正断层型地震,断层面走向近乎南北方向。
Interferometry Synthetic Aperture Radar(InSAR) is a kind of new earth observation technique and makes great development in the recent years.In the paper,InSAR and Differential Interferometric Synthetic Aperture Radar(D-InSAR) are generally introduced firstly.Then Zhongba earthquake is selected as an example to obtain the coseismic deformation field with the two-pass differential interferometric processing method.The results show that it is a shallow dip-slipping predominant normal-fault earthquake,the strike of fault plane is nearly South-North.
