| 英文摘要 | The space cryogenic absolute radiometer (SCAR) is developed at Changchun institute of optics, fine mechanics and physics, in order to satisfy the demands of accuracy and traceability of onboard radiance calibration of spaceborn remote sensors. In this paper, the design decision of SCAR was introduced with emphasis, based on the brief introduction of the state-of-the-art of the cryogenic radiometer benchmark. The working environment of 20 K of SCAR was supplied by a stirling-type cryocooler. The responsivities of total cavity and spectral cavity were designed to be 0.2 K/mW and 1 K/mW by optimizing the structures of cavities and thermal links. The radiance benchmark can be founded by the optical power measurement of 0.02% accurate, which was ensured by close-loop high precision temperature control and electrical substitution measurement procedure with twice electrical heating, as always as the excellent thermal properties of detectors at low temperatures. The radiance standard was transferred to the spectral cavity through temperature comparing, in order to realize the traceable spectral radiometric measurement. This work affords technical reserve for the traceable spectral radiance calibration of spaceborn remote sensors. 2019, Science Press. All right reserved. |
