| 摘 要： | 基于InSAR技术的基本原理,在h=0处进行了泰勒级数展开,推导了干涉相位组成。根据干涉相位组成论证了基线对影像相干性、高度灵敏度、平地效应及干涉SAR系统距离分辨率等的影响,利用数据进行了仿真实验,指出了基线长度对干涉图的影响程度,对合理选择干涉像对具有指导意义。 |
| 关 键 词： | InSAR 基线长度 基线相干 |

| Abstract: | Based on the basic theory of InSAR,the Taylor series expansion in h=0 place is used to derive the interference phase composition.According to interferometric phase composition,this paper analyzes the baselines influence to the image coherence,height sensitivity,flat earth effect,InSAR system range resolution,and so on.The simulation experiment is performed using the actual data,proposing the influence to the Interferogram and the selection of interference with guidance. |
| Keywords: | InSAR baseline length baseline coherence |
