摘要
相位解缠是干涉合成孔径雷达 (INSAR)应用的重要步骤之一。本文通过一定的实验研究 ,对比分析了现有的几种主要的相位解缠算法的原理和特点。路径积分算法的局域算子和最小二乘算法的全局算子是这两类解缠算法的本质特征。而各种不同的算法对不同的数据也各自有其特定的适宜性 ,算法的选择应该视实际数据的特点而定。
Two-dimensional phase unwrapping technology plays a core role in the application of SAR interferometry. The theories and properties of some main unwrapping algorithms are analyzed comparatively with detailed experiment. The local operator of path-following algorithm and the global operator of least-square algorithm are the essential characteristics of the two unwrapping algorithms. Each algorithm has its own unique suitability to different data, and the choice of the algorithms is depended on the data used actually.
