| 摘 要： | 以InSAR和双轨法D-InSAR基本原理为基础,推导出基线误差、卫星平台高程误差、相位测量误差、外部DEM误差以及大气延迟误差对双轨法D-InSAR形变测量影响的关系式,并对这些关系式进行分析,揭示了这些误差对双轨法D-InSAR形变测量影响的规律。

| Abstract: | Based on the basic principles of InSAR and two-track approach D-InSAR,quantitative relations of the effects of baseline error,satellite platform height error,phase error,external DEM error and atmospheric delay error on the deformation measurement of two-track approach are derived and analyzed,General laws of effects of these errors on the deformation measurement of two-track approach are shown. |
