摘  要:
基于云南石林地区2009年4月23日的ALOS PALSAR的L波段全极化散射矩阵单视复数据,利用欧空局PolSARPro软件强大的极化处理功能,首先对数据进行极化分解,然后利用H/α/A—Wishart分类方法对该地区进行分类研究,利用2007年的森林资源二类调查数据作为真实样本数据进行精度检验。结果表明,全极化SAR数据可有效识别出建筑用地、林地、耕地、裸地和水域5种地物覆盖类型,总体分类精度达80.87%。

摘  要:
Based on the perfect polari-metric scattering matrix haplopia data of ALOS PALSAR's L-band at April 23,2009 in stone forest,Yunnan Province,combined with ESA PolSARPro polarization powerful processing software,the data was polarization decomposition,and then using H /α /A-Wishart classification method,this region has been studied and conducted accuracy test by the use of 2007 forest resource inventory data as the real sample data. The results showed that perfect polarimetric SAR data could effectively identify five types' lands of building land,woodland,arable land,bare land and waters area,and the overall classification accuracy was counted for 80. 87%.
