| Abstract: | 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. |
