摘    要:针对早期热红外场景模拟基于机载热像仪图像或随机产生场景的情况,提出针对高分辨率卫星图像进行热红外场景模拟的方法。基于高分辨率卫星图像,采用ISODATA法进行非监督分类,得到土地分类专题图,通过地物光谱数据库获得场景地物温度及发射率,以及大气辐射传输软件MODTRAN对其进行大气修正,从而获得地面场景辐亮度图像。场景仿真结果表明:利用高分辨率卫星图像进行热红外场景模拟是一种全新而有益的尝试,对伪装效果检验等相关研究工作具有一定的参考价值。

关 键 词:卫星影像  热红外  场景  仿真

Abstract:Due to the situation of the early thermal infrared scene simulation software based on airborne infrared imager images or randomly generated simulation scenes, a new method of thermal infrared scene simulation was presented based on high resolution satellite data. Land classification thematic map was obtained by using ISODATA method of unsupervised classification based on high resolution satellite data, was corrected by the atmospheric transmission software MODTRAN, then was converted into a ground radiance image through scene temperature and emissivity based on a ground object spectral library .It is proved that thermal infrared scene simulation based on satellite image is a new approach and helpful for the relevant research works of the camouflage effect evaluation and so on.
Keywords:Satellite image  Thermal infrared  Scene  Simulation
