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-fauh earthquake, the strike of fault plane is nearly South-North.
