摘要
本文提出了一种扫描辐射计可见、近红外通道的辐射定标方法。阐述了定标原理,试验过程及试验结果;并对误差进行了分析。结果表明,以太阳为标准光源,在大气相对宁静的条件下,对扫描辐射计进行定标,可以获得较好的目标光谱特征的反演精度。
In thls paper, a method of radiation calibration for visible and near infrared wavebands of Scanning Radiometer is introduced. The calibration principle, test and results are described, and errors analysed. The results of the radiation calibration test indicate that using the sun as a standard light source, under the condition of stable atmosphere, absolute radiation calibration for visible and near infrared wavebands of VHRSR can be performed with a relatively good retrieval accnraey of target spectral feature for radiometers.
