Review of on-orbit radiometric calibration technology used in infrared remote sensors
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.
