摘要
可见光定标是FY-2气象卫星多通道扫描辐射计研制的关键技术之一,发射前的精确定标是气象资料定量化和数字化应用的主要依据.基于Beer定理,详细说明定标的原理,摸索出一套适合于FY-2扫多通道描辐射计的可见光外场定标方法,建立起定标的规范程序,并对误差来源进行了分类和分析.通过在昆明的多次外场试验,获取了良好的定标结果,验证了这一方法的正确可行.
Abstract
Visible calibration is one of the key technologies for multi-channel scan radiometer (MCSR) on FY-2 geostationary meteorological satellite. Accurate pre-launch calibration is the base and foundation for applications of meteorological information. According to the Beer principle, a set of technique and process fit for FY-2 MCSR are provided and set up to accomplish the outfield visible calibration in Kunming. We also analyze the error and tolerance sources to substantiate and improve our experiment data, which validates that all results are credible and satisfied.
