摘要
利用Radarsat-2与ALOS-2两种卫星SAR数据在新疆乌伦古河地区开展岩性识别研究。通过对Radarsat-2多极化数据和ALOS-2双极化数据进行处理,获取了多类型的SAR影像,对研究区的岩性进行识别。研究表明,综合运用Radarsat-2和ALOS-2影像可实现对研究区的岩性识别,其中,Radarsat-2多极化影像适合对砂岩、凝灰岩等进行识别,而ALOS-2双极化SAR影像提取碳酸盐岩信息效果较好。
Satellite SAR image of Radarsat-2 and ALOS-2 are used for lithology identification in Wulunguhe area,Xinjiang.Multi-polarized Radarsat-2 data and dual-polarized ALOS-2 data were processed to get high quality SAR images used for the lithology identification in study area.Our study shew that combination of Radarsat-2 and ALOS-2 images can identify the lithology in study area.The Multi-polarized Radarsat-2 images are useful for identification of rocks such as sandstone and tuff.Dual-polarized ALOS-2 images were good in extracting carbonate rock information.
