影响InSAR测高精度因素的相关性分析

Related Analysis of Effecting Factors of Height Measurement Accuracy of InSAR

  • 摘要: 从基线沿水平向分解和沿视线向分解的InSAR基本原理出发,分析讨论了InSAR高度测量的精度,详细给出了分解时的斜距、基线、相位以及高度等量的误差之间互不影响和相互影响下对目标高度精度的影响公式。从公式表达可以看出,这些量独立时对目标高度精度的影响是不独立时的特殊情况。

     

    Abstract: Height measurement accuracy is analyzed from InSAR basic theory based on the baseline projection both along horizontal direction and the line of sight direction.The effect formulas of slant range,baseline,phase and height etc.on height measurement accuracy are put forward both mutual influence and non-influence respectively,taking simultaneously into account the baseline projection along horizontal direction and the line of sight direction.It is shown from the formulas that the effect of these independent variables on height measurement accuracy is the special circumstances of non-independence.
