| 摘 要： | 随着对天基对地以及临近空间目标探测的需求增大，高性能红外相机探测及海量数据定量化迫切需要高可靠性、高精度的辐射定标技术，因此，星上辐射定标装置已成为当前空间定量遥感技术发展的重要方向。在轨红外遥感相机的辐射定标主要校正探测器响应的不均匀性（相对辐射定标）和建立遥感相机输出信号与输入辐射量的函数关系（绝对辐射定标）。在介绍红外相机星上辐射定标基本原理的基础上，综述近年来几个国内外典型星上辐射定标装置及其特点，并介绍笔者所在课题组近年来基于内部定标源+天空星图的红外相机高动态范围（HDR）相对辐射定标方法的研究进展。论文对于红外辐射定标技术及星上辐射定标装置的发展具有参考意义。

| Abstract: | With the growing demand of quantitative remote sensing and near-space target detection technology, the radiometric calibration technology with high reliability and high accuracy, the on-orbit radiometric calibration device has become an essential orientation in quantitative remote sensing. The on-orbit radiometric calibration of an infrared remote sensing system includes non-uniformity correction(relative radiometric calibration) and absolute radiometric calibration. Absolute radiometric calibration is defined in terms of a sensor's response on a physical, real-world scale, measured in internationally defined units. Based on the introduction of the basic calibration principles, the latest development in infrared on-orbit radiometric calibration devices was reviewed and the technical features of the radiometric calibration method was analyzed. Furthermore, our recent research progress was introduced based on internal calibration sources and combined with starring image in high dynamic range(HDR) relative radiometric calibration methods was introduced. The research promotes the development of infrared on-orbit radiometric calibration devices and technology. |
