海洋水色卫星遥感的关键是水色图像资料的利用率。受到太阳反射光的影响使图像饱和是水色卫星图像的主要噪声之一。笔者首先论述了卫星海洋水色遥感中到达水色扫描仪的太阳反射光(即太阳耀光)的辐射量计算模式;然后介绍了产生太阳耀光模拟图像的全过程,并对我国FY-1B、美国的SeaSTAR和台湾省的ROCSAT-1号卫星作了全轨道下的太阳耀光模拟图像;最后,讨论了影响太阳耀光的主要因素,同时提出了减小太阳耀光提高海洋水色卫星遥感图像利用率的建议。
The key to ocean color satellite remote sensing is the utilization of aqua image data. Saturation of the image by the influence of the sun’s reflected light is one of the major noise of aqua satellite images. The author firstly discusses the radiation quantity calculation mode of solar reflected light (that is, solar flare) that arrives at the aqua scanner in satellite ocean color remote sensing. Then the whole process of generating solar flare simulation image is introduced, and the FY-1B, SeaSTAR and Taiwan’s ROCSAT-1 satellite made full-orbit simulation of solar flares. Finally, the main factors affecting the solar flare were discussed. At the same time, the paper proposed to reduce the solar flare and improve the utilization of ocean color satellite remote sensing images Rate the suggestion.
