摘要
介绍和比较了现有的3种常用相位解缠算法,同时提出一种改进经典残差缺口解缠算法:由GPS高程转换的可靠相位值在解缠过程中能帮助正确设置枝切路径及起算点,避免低质量区域的误差对高质量区域解缠结果产生影响,即使在噪声大的地区亦能获得较理想的解缠结果。
Three kinds of phase unwrapping algorithms：Residue-cut, Least-squares and Network-flow algorithm in common use today are reviewed and compared. Besides, a modified phase unwrapping algorithm of Residue-cut is proposed. By converting GPS heights to the proper phases in the unwrapping, this algorithm can help us identify the location of branch cuts and initial points properly, avoid the influence of the low-quality zones on the high-quality ones and unwrap the zones with high noises so as to get a better result.
