| 摘 要： | 雷达差分干涉测量（D-InSAR）技术以其高精度检测雷达视线向形变量的特性，在地学界得到广泛应用。利用三轨法D-InSAR技术提取1997年11月8日西藏玛尼地震的部分垂直形变和水平形变，结果表明：断裂为左旋扭动态势，北盘最大垂直位移约0．7m，南盘最大垂直位移约0．8m，北盘最大水平位移约1．6m，南盘最大水平位移约2．4m。表明三轨法DInSAR技术用于探测地震形变的巨大潜力和优势。 |

| Abstract: | Differential SAR Interferometry（D-InSAR） could measure look-of-sight displacement precisely and is used widely in geomatics. This paper attains the vertical and horizontal deformation of Mani earthquake at November 8, 1997. The maximum vertical deformation and horizontal deformation of the northern rupture part are about 0.7m and 1.6m respectively, and the counterpart of the southern rupture part are about 0. 8m and 2. 4m. The rupture is left-lateral. This result indicates that DInSAR is potential in detecting deformation of earthquake. |
