【摘要】：该报告介绍了2013年度该课题在机载极化干涉SAR系统构建、高分辨率SAR遥感综合实验、高分辨率SAR遥感应用示范软件开发等方面的研发进展。在机载极化干涉SAR系统构建方面,完成了X-波段干涉SAR传感器的研制,进行了SAR系统的实验室联调测试和机载校飞试验。先后在四川若尔盖实验区和大兴安岭根河实验区开展了高分辨率SAR遥感综合实验,共获取8 619.8km2,约28.5TB的机载X-波段双天线In SAR和P-波段极化SAR数据,完成了所获取SAR数据的预处理;获取了覆盖大兴安岭根河实验区的多时相Radarsat-2极化SAR和Landsat-8多光谱卫星遥感数据;组织来自项目8家课题承担/协作单位的50多人次,参加了遥感同步、准同步调查工作,获取了森林叶面积指数(LAI)、农田植被参数、土壤参数、气象参数以及土地覆盖类别等的地面实况数据。在高分辨率SAR软件开发方面,已初步完成地形测绘、土地利用分类、植被覆盖类型分类和森林植被垂直结构参数估测等软件模块原型的开发,正在按统一的语言和标准进行完善和集成,以尽快形成界面友好的高分辨率SAR应用示范软件,为2014年的应用示范工作开展提供软件支撑。
[Abstract]:This report introduces the research and development of airborne polarization interferometry (SAR) system, high-resolution SAR remote sensing experiment, and demonstration software development of high-resolution SAR remote sensing application in 2013, and the construction of airborne polarimetric interferometric SAR system. The X- band interferometric SAR sensor has been developed, and the SAR system has been tested in laboratory and airborne flight correction. The high resolution SAR remote sensing experiments have been carried out in the Ruoerge experimental area of Sichuan Province and the Genhe experimental area of Daxing'anling in Sichuan Province, respectively. A total of 8 619.8km2, about 28.5TB of airborne X-band dual-antenna in SAR and P- band polarized SAR data were obtained, the preprocessing of the obtained SAR data was completed, and the multiphase Radarsat-2 polarized SAR and Landsat-8 multispectral satellite remote sensing data covering the experimental area of the Great Xingan Mountains were obtained. More than 50 people from 8 project undertaking / collaborating units were organized to participate in remote sensing synchronization and quasi-synchronous investigation, and obtained forest leaf area index (Lai), farmland vegetation parameters, soil parameters, In the development of high-resolution SAR software, topographic mapping and land use classification have been preliminarily completed. The development of prototype software modules, such as classification of vegetation cover types and estimation of vertical structure parameters of forest vegetation, is being perfected and integrated according to the unified language and standards, so as to form a high-resolution SAR application demonstration software with friendly interface as soon as possible. Provide software support for the application demonstration in 2014.
