| 摘 要： | 从三轨法D-InSAR基本原理和数据处理流程出发，分析讨论了相位测量误差对三轨法D-InSAR形变测量精度的影响，详细给出了相位测量误差对三轨法形变测量影响的定量关系式。从定量分析中可以看出，基线比是造成相位测量误差对三轨法形变测量精度影响的一个关键因素，同时，卫星视角也是影响三轨法形变测量的一个比较重要的因素。

| Abstract: | Effecting of phase error on three-pass D-InSAR deformation measurement is analyzed from the basic principle and flow chart of data processing .The quantitative formu-las of phase error and three-pass D-InSAR is put forward in detail .It is shown from quantita-tive analysis that baseline ratio is key factor in effecting of phase error on three-pass D-In-SAR deformation measurement and visual angle of satellite is an important factor in three-pass D-InSAR deformation measurement . |
