摘要
相位解缠是合成孔径雷达(SAR)干涉测量数据处理的重要步骤之一。解缠的精度将直接影响干涉测量结果的精度,本文通过实验研究,对比分析了现有的两类主要的相位解缠算法的解缠原理、解缠思想、各自的特点及其引起误差的原因,然后结合各自的优点组成了一种效果更好的二维相位解缠算法。使用该算法解缠后的相位条纹与原始干涉相位图相位条纹的一致性非常好。
Phase Unwrapping is one of the important steps in data-processing of Synthetic Aperture Radar (SAR) interferometry.The accuracy of unwrapping will directly affect the accuracy of interferometry.Through experimental studies,the paper firstly compares the two existing main algorithms of Phase Unwrapping on unwrapping principles,unwrapping ideas,characteristics and reasons causing an error as well,and then forms a better two-dimensional phase unwrapping algorithm by combining respective advantages.By making use of the new algorithm, the phase stripe unwrapped has a very high consistency with the original phase stripe of Interference phase diagram.
