合成孔径雷达数据可提供补充信息，改进城市不透水面的测绘。然而，大多数研究都集中在仅使用单极化SAR数据。本文介绍了一个比较研究的多光谱光学数据和双极化SAR数据的组合使用，以识别城市不透水面。利用SPOT-5、TerraSAR-X和ALOS PALSAR数据的实验结果与我们以前利用单极化SAR数据的实验结果一致。双重结果表明，极化合成孔径雷达图像一般上级单极化合成孔径雷达数据提取不透水表面区域，虽然不是每个人的极化功能可以提供一个积极的结果不透水表面映射。与仅使用光学和SAR数据相比，分离的HH和HV极化数据提高了结果的准确性。熵和Alpha特征的结合也提高了准确性。然而，HH/HV比率和单独使用相干性没有提供积极的结果。值得注意的是，所有的双极化合成孔径雷达功能的组合能够获得最佳的精度，与仅使用SPOT-5图像相比，提高了约3.5%。这一结果表明，双极化SAR数据优于单极SAR数据的城市不透水面测绘。
Synthetic aperture radar (SAR) data can provide complementary information to improve the mapping of urban impervious surfaces. However, most studies have focused on using only single polarization SAR data. This paper presents a comparative study on the combined use of multispectral optical data and dual polarization SAR data to identify urban impervious surfaces. The experimental results using SPOT-5, TerraSAR-X and ALOS PALSAR data were consistent compared with our previous results using single polarization SAR data. The two-fold result showed that polarimetric SAR images were generally superior to single polarization SAR data for extracting impervious surface areas, although not every individual polarimetric feature could provide a positive result for impervious surfaces mapping. Compared with using only optical and SAR data, the separate HH and HV polarization data improved the accuracy of the results. The incorporation of both Entropy and Alpha features also improved the accuracy. However, the HH/HV ratio and the separate use of coherence did not provide positive results. Noticeably, a combination of all of the dual-polarimetric SAR features was capable of obtaining the best accuracy, with an improvement of approximately 3.5% compared with that of only using SPOT-5 images. This result indicates the superiority of dual-polarimetric SAR data over single polarimetric SAR data for the mapping of urban impervious surfaces.
