| 摘 要： | 提出一种新的干涉相位图滤波方法，并设计了一种自适应Gabor干涉图滤波器；这种滤波方式克服了传统线性相位在低信噪比条件下采用大窗口滤波带来相位失真，能够更加准确地区分局部干涉信号与相位噪声，有效地抑制了相位噪声的同时最大限度的保持了真实的相位信息；仿真和实际数据的处理结果验证了本方法的有效性。

| Abstract: | In this paper, a new method of interferometric phase images filtering is given, and a kind of a-daptive Gabor filter interferograms is designed. This way of filtering overcomes the traditional linear phase under the condition of low signal-to-noise ratio with large window filtering phase distortion. It can distin-guish more accurately between local interference signals and phase noise, inhibit the phase noise effectively at the same time and retain a maximum of the true phase information. The simulation and real data pro-cessing results show the effectiveness of this method. |
