质量图引导的相位解缠算法是一种路径跟踪的算法,本文在三种经典相位质量图分析基础上,分别应用不同质量图引导的相位解缠算法对陡峭地形和平坦地形条件下的InSAR数据进行相位解缠实验,实验结果表明,对于地形陡峭的数据选取相位导数方差得到的结果最可靠,而地形平坦数据选取伪相干系数图能够得到较为精确的结果。
The phase unwrapping algorithm guided by the mass map is a path-tracking algorithm. Based on the analysis of the three classical phase-quality maps, the phase unwrapping algorithm guided by different quality maps is applied to the InSAR data of steep and flat terrain The phase unwrapping experiment is carried out. The experimental results show that the result of selecting the phase derivative variance for the data with steep steepness is the most reliable, while the pseudo-coherence coefficient map of the flat terrain data can obtain more accurate results.
