Radiometric calibration (RC) guarantees measurements from infrared photonic sensors with certain accuracy, where a traditional radiation source will introduce unexpected uncertainties for degradation. To overcome such a limitation, Scientist in China proposed an original source independent RC (SIRC) principle by modeling the incident background radiation to both photoconductive and photovoltaic HgCdTe detectors, respectively. SIRC will ensure a long-term stable service of Chinese geostationary meteorological satellites and benefit the future infrared micro-satellite constellation for climate applications.
