摘要
着重介绍了宽通道红外遥感器对应通道间的交叉辐射定标光谱匹配方法,并以FY-2CIR1、IR2与Terra/Aqua MODIS 31、32通道为切入点,进行通道间的光谱匹配计算,获取了两通道的光谱匹配因子,为实现这两种传感器红外分裂窗通道的交叉定标奠定了基础。该方法可以很好地应用于各种类型卫星红外遥感器的对应通道间交叉定标光谱匹配,为实现不同类红外遥感数据的辐射归一化提供了重要的方法借鉴,为建立一致的全球红外遥感观测数据库奠定了基础。
The method of spectral matching for broadband infrared channels of remote sensors was intro- duced in this paper. The channels of FY-2C＇s IR1 ,IR2 and Terra/Aqua MODIS 31,32 were selected as example to do spectral matching, calculate the matching coefficients for corresponding channels. All of these efforts were set the seals on the inter calibration of two sensors. This method can be used for all kinds of infrared remote sensors corresponding channels inter calibration spectral matching and also provide a good methodology for the radiometric normalization in the different types of infrared remote sensors. This method can be used to establish the uniformed globe infrared remote sensing database.
