摘要
“风云二号”(FY-2C)的主要载荷是自旋稳定平台上的多通道扫描辐射计。卫星进入午夜工作时,太阳光线将会入射到辐射计的R-C光学系统中,并且经过各种器件及框架结构反射或者漫反射,从而产生影响成像的杂散光。针对气象部门提供的FY-2C卫星云图中午夜杂散光较严重的情况,分析了特定噪声区域的产生原因,并为同型号卫星星载扫描辐射计的改进提供参考性建议。
The multispectral channel imager on spin-stabilized platform is main payload of FY-2C meteorological satellite. Sunlight into the Ricci- Chrétien（R-C） optical system when satellite works around midnight results in reflex or stray radiation from the optical component or the optical support structure causing bad imaging： quality. The reasons of specifically noisy area were analyzed in some bad imaging quality nephograms offered by weather del^rtment. Some suggestions are given for betterment of the imager in the same model satellite.
