| 摘 要： | 提出了一种由低空飞行获取的以红外图像为数据源的中远红外仿真方法。首先通过大气辐射传输模型计算出测量条件下的程辐射和大气透过率,反演出地面温度,然后再由大气传输模型计算出仿真条件下的程辐射和大气透过率,并仿真卫星高度下的红外图像。以飞艇为平台,并搭载中远红外成像系统进行飞行,对获取的数据进行仿真模拟。试验结果表明,这种利用大气辐射传输模型和基于低空成像信息的遥感图像仿真方法可以用于模拟相同地区相同波段范围的卫星图像。 |

| Abstract: | A simulation method of infrared image is mentioned.First,the IR image obtained by low-level flight is accepted as data resource;the path radiance and transmission are calculated at current condition using atmospheric transmission model.After that the temperature of ground is deduced.Then the path radiance and transmission at simulated condition are calculated again using atmospheric transmission model.Finally,the IR image at satellite height can be simulated.An experimentation is carried out to test the met... |
