本文提出了一种基于有选择保边缘平滑的合成孔径雷达干涉图像相位噪声抑制的算法。该方法以方差作为各个邻域均匀性的测度,分别对干涉图的实部和虚部进行平滑处理,不仅可以有效地抑制SAR干涉图的相位噪声,较好地保持边缘细节,而且处理所得的图像结果有着良好的视觉效果。
In this paper, an algorithm for phase noise suppression of synthetic aperture radar interferometric images based on selective edge-preserving smoothing is proposed. In this method, the variance is taken as a measure of the uniformity of each neighborhood, and the real and imaginary parts of the interferogram are smoothed separately. This method not only can effectively suppress the phase noise of the SAR interferogram but also keeps the edge details better, Image results have a good visual effect.
