| 摘 要： | 多基线InSAR具有高可靠性与高精度的优势,是InSAR技术发展的方向之一。为了提供研究多基线InSAR技术的良好实验数据,针对正侧视SAR成像的几何特点,以F.Leberl构像模型建立像点与地面点之间的坐标关系,借鉴摄影测量中的正射纠正方法,分别设计了利用DEM进行多基线InSAR干涉图模拟的直接法仿真方案和间接法仿真方案。采用多套DEM进行了仿真实验,得到了满意的仿真效果,结合仿真结果分析了不同仿真方案的特点。

| Abstract: | Multi-baseline InSAR has the advantage of good reliability and high precision.So it is a new direction of InSAR.In order to improve test data for study of Multi-baseline InSAR,interferograms simulation methods for Multi-baseline InSAR were designed.Aiming at the geometrical feature of right side-looking SAR images,the relationship between coordination of ground point and interferogram pixel was formed by F.Leberl imaging model,the direct simulation method and indirect simulation method of interferograms were designed with reference to ortho rectification in photogrammetry and remote sensing.The satisfying interferograms were got by simulation experiments,as validated the simulation project was right and valid.The characteristic of these two simulation methods was analysed based on the simulation interferograms. |
