Two-Dimensional Phase Unwrapping for Interferometric SAR Based on Local Minimum Spanning Tree
基于局部最小生成树的干涉SAR二维相位展开

In this paper, a new approach to two-dimensional phase unwrapping for in-tcrferometric SAR based on local minimum spanning tree is presented deriving by branch optimum model. This approach avoids separated intcrferogram into isolated regions resulting in incomplete unwrapped phase by traditional connecting residues methods. Guided by quality map, the connecting of residues is proposed exactly and optimized. The experiments onreal interfcrogram show the validity of this approach.
