本文分析了二维相位展开算法的特点,探讨了基于干涉图质量参数的相位展开方法。按干涉图质量优劣排序,对InSAR干涉图进行相位展开,可以有效减小截断相位中无效点对相位展开结果的影响。文中给出了算法的详细描述,以及按干涉图质量参数排序进行相位展开的实验结果。
The algorithm of phase unwrapping - 2D is analysised in the paper, and algorithm based on the quanlity parameter of interferogram is discussed. By this method, intefferogram is unwraped, the effect of the points of bad or non - phase information to unwrapping phase of valid points can be reduced greatly. A good result of the phase unwrapping is obtained, this shows the particular bewrite of phase unwrapping algorithm based on the quanlity parameter of interferogram.
