摘要
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。
It is a crihcal problem for availability of data in satellite ocean colourremote sensing, which is mainly affected by the reflected sunlight from water surface.The paper flrst describes the models of calculahng the radiance of reflected sunlight(so called sun glit) reached to the satellite scanner, and introduces the procedure ofsimulahng whole orbit image of sun glit. The radiant images of sun glitter of Chinesesatellite FY-1B, American satellite SeaSTAR and satellite ROCSAT-1 of TaiwanProvince are also simulated and presented. Rnally, the main factors affecting sunglitter are discussed and some techniques are suggested to reduce sun glit in order tohave more efficient data from ocean colour satellite.
