摘要
分析了照相机和地基毫米波辐射计的成像机理,讨论了光学图像的分割和识别方法,论述了地物表面温度亮温、视温、天线温度和天空温度之间的关系,并在此基础上提出了一种用可见光图像模拟生成毫米波辐射图像的方法.该方法用于制作地图匹配制导中的基准地图.图像模拟的结果表明,该方法完全可行.
Abstract
Imaging principles of a camera and a grand based millimeter wave radiometer were analyzed. Segmentation and recognition methods of optical images were discussed. The temperature and brightness relations between the terrain surface and sky were discussed .The method of computing the antenna temperature of the terrain was given. Therefore a new technique to generate the grand based millmeter wave radiometric images from visual optic images was presented. The technique was expected to be a useful tool to generate reference images of the matching navigation. Experimental results show that the technique is completely practicable.
