【摘要】 本文用实例研究了我国引进的C波段机械合成孔径侧视雷达图像在不同地域范围、不同地貌类型条件下的比例尺、点位、线段和面积误差。并在此基础上,根据该雷达图像的影像特征,建立了雷达图像的土地和森林类型分类系统和判读标志,进行了土地和森林类型的判读及森林区划的试验。研究结果表明,该图像已具有一定的几何精度,有较好的可供作境界线、林班线区划的地性线信息,以及土地和森林类型的可判性。因此,我们认为,它在森林资源调查及动态监测等方面具有一定的实用价值。更多还原

【Abstract】 In this paper, with a real example, we examined the images of Band C of the imported Airborne Synthetic Aperture Side-Looking Radar and the errors in scales, points, lines and areas in different regions in case of different geomorphological conditions. Additionally, based on the features of the radar images, land and forest type classification systems and markings for interpretation are set up. Experimental work is conducted on interpretation of land and forest types as well as forest regionalizations. The results show, as for as the images concerned, they possess considerable geometric accuracy and provide better information on boundary and compartmental lines and the ability of distinguish for land and forest types. Therefore, they are considered to have practical value in forest resources inventory and dynamic monitoring.更多还原
