A robust two-dimensional continuous wavelet transform (2D-CWT) technique for interferogram analysis is presented. To cope with the phase determination ambiguity issue encountered in the analysis of complex interferograms, a phase determination rule is proposed according to the phase distribution continuity, and a frequency-guided scheme is employed to obtain the correct phase distribution following a conventional 2D-CWT analysis. The theories are given in details, and the validity of the proposed technique is verified by computer simulation and real experiments.
提出了一种用于干涉图分析的稳健二维连续小波变换（2D-CWT）技术。为了解决在复杂干涉图分析中遇到的相位确定模糊问题，根据相位分布的连续性提出了一种相位确定规则，并采用频率引导方案在传统二维连续小波变换分析之后获得正确的相位分布。详细阐述了这些理论，并通过计算机模拟和实际实验验证了所提技术的有效性。
