摘　　要：提出了一种改进的最小不连续相位解缠算法.根据相位质量图将缠绕相位分为高、低质量区域,高质量区域采用质量引导算法进行相位求解,有效保持了高质量区域的相位解缠精度,低质量区域进行最小不连续优化.对真实InSAR干涉图的处理结果表明,文中方法在提高相位解缠精度的同时极大优化了相位解缠速度.In this paper, an improved minimum discontinuity phase unwrapping algorithm is proposed. The wrapped phase is divided into high and low quality regions according to its quality map firstly, then the high quality regions are unwrapped by the quality-guided phase unwrapping algorithm, which keeps the accuracy of the unwrapped phase in high quality regions, and the minimum discontinuity phase unwrapping algorithm is performed on the low quality regions. The experiment result with real InSAR data shows that the proposed algorithm improves the accuracy of the unwrapping result and ac- celerates the unwrapping process.
