| 英文摘要 | With the increasing requirements for quantification of in-orbit data products, the research of high-precision calibration system is of vital importance. Based on the research background of Tiangong-2 (TG-2) Wide-band imaging spectrometer payload, a complete scheme of full detection band radiometric and VNIR spectral calibration is proposed in this paper. A full FOV and aperture calibrator with internal reference radiation sources is designed, which consists of pointing mirror, halogen lamp with Pr-Nd glass and surface blackbody, and calibrates by rotating the mirror to point to the lamp and blackbody. The results of in-orbit calibration show that the scheme is reasonable and the calibration accuracy meets the requirements. |
