SBAS-InSAR主影像选取方法研究与探讨

Research and Discussion on the Method of SBAS-InSAR Main Image Selection

通过对现有的小基线集技术(SBAS-InSAR)主影像选取方法进行分析,提出了基线均衡化的主影像选取方法。在时间基线优选原则的基础上,有效地对三基线进行均衡化,利用三基线和最小原则,选取SBAS-InSAR主影像。该方法具有容易实现、计算快速、可集成性等特点。

Based on the analysis of the main image selection methods of the existing small baseline set technology （SBAS-InSAR）, a method of selecting the main image for baseline equalization was proposed. On the basis of the principle of time baseline optimization, the three baseline was effectively balanced, and the three baseline and the minimum principle were used to select the main SBAS-InSAR image. The method is easy to implement, fast and integrated.
