摘要
近年来机载SAR系统在国内得到快速发展。由于SAR系统具有不同于光学传感器的成像机理,因而可以提供全新的数据获取手段和不同的地物信息。利用高分辨率机载SAR影像进行解译时必须熟悉其成像机理和图像信息特点,充分了解SAR图像解译标志的特点和各类地物的解译规律。本文以高分辨率机载SAR数据为基础,对比光学影像,从SAR成像特点和地物散射特性出发,对SAR影像进行了目视解译,分析了SAR影像在地形地物要素识别中的应用潜力。
Due to the advantage of all-weather and all-time,AIRSAR system has rapid development in China.Because of the different imaging pattern and imaging mechanism compared with optical sensor,SAR system could provide brand-new means to acquire data and different object information.It's necessary to be familiar with the imaging mechanism and image information characteristic through interpreting SAR images.On this foundation,it is extremely important that the characteristic of SAR image's interpretation symbols and each kind of ground object's interpretation rules are comprehended sufficiently.The paper bases on the airborne radar image data in China and carries on the Visual Interpretation which is compared by optical images in the same areas.And then according to the characteristics of the microwave and the ground object scattering properties,it analyzes how to recognize the terrain elements in the SAR image and its application potential.
