利用干涉技术定权建立巴姆地区三维形变场
|
摘要
针对传统合成孔径雷达差分干涉测量技术(D-InSAR)只能得到地震区域在雷达视线方向的形变量,即竖直、东西、南北三个方向形变在雷达视线方向的投影,而在研究地震时一维形变量不能满足需求和D-InSAR技术对南北向极不敏感的问题,利用多孔径合成孔径雷达干涉测量技术在监测南北向形变量中的优势与D-InSAR技术在监测垂直方向的形变量中的优势相结合,并用形变图方差法对这两项技术进行定权,建立了伊朗巴姆地区的三维形变场。
The deformation of the seismic zones got by traditional D-InSAR technology is the deformation in direction of radar line-of-sight,which is the projection of vertical,east-west,north-south deformation.It is far less enough to know the unidimensional deformation in studying the earthquake.Furthermore,D-InSAR technique is not sensitive to the north-south direction deformation.In this paper,this problem was well solved by combining the advantage of the Multiple Aperture InSAR in north-south direction and the D-InSAR technique in vertical direction.Finally,the result was weighted by deformation images standard deviations and then the three-dimensional deformation field of the Bam region was created.
