摘要
本文在分析均值滤波、圆周均值滤波、中值滤波、自适应中值滤波、二维自适应滤波和不规则窗口自适应中值滤波方法对模拟数据干涉图纹图进行滤波去噪处理的效果的基础上,引入综合滤波去噪方法,使用该滤波去除方法对真实数据InSAR干涉图进行滤波去噪处理,并对结果从定性和定量两个方面进行分析讨论。实验结果分析表明,InSAR干涉图综合滤波去噪方法是有效和可行的。
Based on analyzing the effect of mean fihering, circular mean filtering, median filtering, adaptive median filtering, two-dimensional adaptive filtering and irregular window adaptive median filtering for the interference pattern graph of analog data, the integrated filter was introduced in the paper. The noise from the interference graph of real data InSAR was filtered, whose result was analyzed on term of both the qualitative and the quantitative aspects. The validity and feasibility of the integrated filtering was shown by the experiment result.
