摘要：

Phase unwrapping is one of the most difficult processing steps in sar interferometry. In this paper a new phase unwrapping approach based on minimum spanning tree is proposed. To discharge the positive and negative residues, all residues are divided into groups in a systematic searching strategy, and the connecting of residues in each group is optimized based on minimum spanning tree, optimum branch trees are achieved. The technique is explained in detail, the experiments prove the new algorithm more efficient than Goldstein's branch cut algorithm.
