主星带小卫星分布式SAR干涉的相对测高精度分析

Analysis of Relative Height Accuracy for Master Satellite and Distributed Small Satellite SAR Interferometry

  • 摘要: 相对测高精度是干涉SAR测高性能的重要指标之一。该文根据主星带小卫星分布式SAR系统的实际空间几何条件下建立了干涉测高原理;基于相对测高几何,推导了相对测高精度与干涉相位误差的关系式;理论分析了基线去相关、图像配准误差去相关、热噪声去相关等,并推导了图像相关系数;最后,仿真分析了图像去相关因素对于主星带小卫星分布式SAR干涉的相对测高精度影响。结果发现:对于平坦地形来说,热噪声与配准误差是影响相对测高精度的主要因素,而基线去相关影响相对较小。
