| 摘 要： | 干涉参数定标对于机载双天线InSAR系统的大面积高精度数字高程模型获取具有重要意义。为了高效地进行干涉参数定标,从双天线InSAR获取DEM的基本原理出发,构建一种考虑干涉相位偏置、基线长度和基线水平角三个参数的定标新模型,设计该定标模型的未知参数解算方案。利用GPS实测的高程控制点对中国科学院电子学研究所自主研制的机载双天线InSAR系统进行了干涉参数定标实验,统计利用定标后干涉参数反演地面高程的误差,验证该干涉参数定标模型及解算方案。

| Abstract: | It is significant to calibrate interferometric parameters of dual-antenna airborne InSAR systems for deriving accurate DEM with large areas. A new calibration model considering phase offset,baseline length and baseline angle was proposed in order to calibrate interferometric parameters effectively,which was induced from the basic theory of DEM deriving from InSAR. And its solution scheme was designed. The calibration experiments of interferometric parameters were done with height control points measured by ... |
