SWIR光谱仪辐射定标数据集(2021年)

短波红外波段（SWIR）光谱仪辐射定标的任务是在光谱仪的数字化输出与地面景物光谱辐亮度之间建立定量关系。SWIR光谱仪辐射定标数据集中包含了60个亮度等级的辐射定标数据文件，每一个数据文件记录了大约200帧的图像数据，通过辐射定标数据可以表征SWIR光谱仪在不同亮度条件下的响应特性，对于仪器的关键的性能指标，例如信噪比和辐射响应度、辐射线性度等，均可由该数据集计算获得。

The task of radiometric calibration for Short-Wave Infrared (SWIR) spectrometers is to establish a quantitative relationship between the digital output of the spectrometer and the spectral radiance of ground scenes. The SWIR spectrometer radiometric calibration dataset includes radiometric calibration data files for 60 brightness levels. Each data file records approximately 200 frames of image data. These radiometric calibration data can be used to characterize the response characteristics of the SWIR spectrometer under different brightness conditions. Key performance indicators of the instrument, such as signal-to-noise ratio (SNR), radiometric responsivity, and radiometric linearity, can all be calculated using this dataset.
