一种基于残差点分布的FMCW InSAR阴影区域提取方法
A Shadow Area Detecting Approach Based on Residue Distribution
摘要
Abstract
For airborne FMCW InSAR system,the shadow phenomenon can be considerably serious due to the side-look imaging mechanism in fluctuant areas,affecting the quality of DEM and DOM.The method based on correlation coefficient relies on the threshold which is usually hard to choose.In view of this problem,a shadow area detecting approach based on residue distribution is proposed.Based on the analysis of the formation mechanism of residues,a combination of the phase residue distribution and the morphological processing is used to detect the continuous shadow areas.Compared with the traditional method based on correlation coefficient,this approach solves the problem of threshold dependence.Finally,the effectiveness of the proposed method is verified by comparing the results obtained using the approach based on correlation coefficient.关键词
