摘要:
红外辐射定标是红外遥感信息定量化的关键技术,对所测光谱进行定标是定量分析中的重要环节。采用自行研制长波红外高光谱成像光谱仪原理实验装置(简称CHIPED-I)进行验证,用黑体对实验装置进行了两点线性定标,将测量的相对强度转化成目标的绝对辐射亮度谱,采用亮温法算出标定后的亮温光谱。结果表明,这种辐射定标方法用于长波红外高光谱成像光谱仪方法可行,这对进一步分析大气透过率和反演大气中红外活性气体浓度具有实际意义。
Abstract:
Infrared radiometric calibration is of critical importance for information quantification of remote sensing of environment in infrared spectrum. In the quantitative analysis, the calibration of the measured spectra is very imporant. LWIR Interferometric Hyperspectral imager Spectrometer Prototype(CHIPED- I) is developed for studying Radiation Calibration. Two-point linear calibration method is carried out for the spectrometer by using blackbody respectively. Firstly, relative intensity is converted to the absolute radiation lightness of the object. Then, radiation intensity of the object is converted into the brightness temperature spectrum by the method of brightness temperature. The result indicats that such method of Radiation ?Calibration calibration is very good,which is of significance to the further analysis of atmospheric transmission and the retrieval of the concentration of infrared active gas in atmosphere.
