| 摘 要： | 论述了InSAR系统平地效应产生的原因,并简述了去除平地效应的常用方法：基于轨道、基于DEM及基于频率的平地效应去除方法。分别将这三种方法应用于机载InSAR系统,经实验结果对比分析表明：基于频率的方法不适用于机载系统,基于轨道、基于DEM的方法适用于机载系统,并得到了满意的结果。 |

| Abstract: | The cause of flat-earth effect in InSAR system was discussed in the paper,and the common methods of removing the flat-earth effect were described：one method based on orbit,one based on DEM and another based on frequency.The three methods were respectively applied to airborne InSAR system.The results show that the two approaches based on orbit and DEM are suitable for airborne systems,while the other approach based on frequency is not fit for airborne system.And the first two methods are satisfactory. |
