摘要: 给出了干涉雷达位相构成的表达式,其次对干涉雷达的数据处理方法进行了比较分析并且对一些数据处理应注意的问题进行了阐述;最后以1997年11月8日西藏玛尼发生的7. 5级地震前后的ERS-1/2干涉雷达数据为基础,介绍了干涉雷达在获取西藏玛尼地震同震位移场中的应用。

关键词: 差分干涉雷达, 差分干涉条纹, 同震位移场

Abstract: Firstly, a formulation of the phase constituent of interferometric SAR is presented, which is important tounderst and the data processing of interferometric SAR; secondly, data processing methods of interferometric SAR are compared and analyzed, furthermore, some problems that should pay attention to when the data processing are implemented are introduced. At last, basedon the EAR-1/2 interferometric SAR data before and after the Mani earthquake with M= 7. 5 on 8 Novem ber 1997, this paper introduced the ba sic theory that use differential interferometric SAR to extract the surface deformation field.

Key words: Differential interferometric SAR, Differential interfero gram, Coseismic displacement field
