摘要
文章介绍了HJ - 1A卫星CCD相机的任务需求 ,分析了影响CCD相机入射光谱辐射亮度的主要因素 ,通过“6S”软件得到在不同条件下CCD相机入射光谱辐射亮度 ,并依据CCD相机各波段的观测能力与地物的光谱特点 ,最终确定了CCD相机各波段不同增益对应的最大入射光谱辐射亮度。
The task and requirement of HJ-1A satellite CCD camera are introduced, then the paper analyzes chief elements which effect on the incident spectral radiance of HJ-1A satellite CCD camera And get different incident spectral radiance of CCD camera in different conditions through '6S' software According as the observation ability of every waveband and the spectral characteristic of ground, the maximum value of incident spectral radiance of every waveband is finally given
