【摘要】 FY-2扫描辐射计是我国风云二号静止气象卫星的有效载荷之一。本文主要介绍利用辐亮度法对扫描辐射计发射前进行可见光通道室外定标,这种定标方法以辐射标准为基础,通过辐射标准的传递,确立扫描辐射计输入和输出的关系。本文也对定标原理、定标过程以及结果计算分析进行了比较详细的论述,最后也对定标过程提出了一些改进意见。更多还原

【Abstract】 FY-2 scanning radiometer is one of FengYun-2 still weather satellite availability loads. This paper mainly introduces visible light calibration of scanning radiometer before launch. Calibration method based on radiometric standard established the relationship between input and output of the scanning radiometer through transfer of radiometric standard. Calibration principle,calibration process and calculation result are also discussed in detail. Finally,some improved opinion for calibration process is given.更多还原
