“基线”是干涉合成孔径雷达（InSAR）中最重要的参数之一。基线估计的精度对InSAR产品的质量影响很大。本文提出了一种改进基线估计的新方法。该方法估计基线的主要优点是无需相位展开和地面控制点（GCP）即可进行计算。最终结果表明，使用所提出的基线估计方法可以生成更好的差分干涉图。
The ‘baseline’ is one of the most important parameters in Interferometric Synthetic Aperture Radar (InSAR). The quality of InSAR products is significantly affected by the accuracy of baseline estimation. In this paper, a new approach to improving the baseline estimation is proposed. The main advantage of estimating baseline by the proposed method is that the calculation can be performed without the need for phase unwrapping and ground control points (GCPs). The final result shows that a better differential interferogram can be generated using the proposed baseline estimation method.
