中文摘要：

质量图指导算法是以相位质量图作为指导，从高质量的像素点开始解缠逐渐扩展到低质量的区域，亦可从多个区域同时解缠最后达到整体解缠，此类算法的关键就是选取合适的相位质量图对解缠过程进行指导。选取3种质量图对模拟数据及真实InSAR数据进行质量图指导法解缠分析，结果表明伪相干系数图具有较好的特性。

英文摘要：

Quality-guided phase unwrapping algorithm is one of the most effective methods. In this category of algorithms, the pixels are unwrapped from the high quality points to the low quality ones. The success rate of phase unwrapping strongly depends on the quality map. We employ three quality maps （i. e. , pseudo-correlation, phase derivative variance map and maximum phase gradient） as the guided maps and make some comparative analyses among them aiming to indicate which map performs best in general case.
