摘　　要：国内已知的红外星库数量有限，辐射照度、覆盖波段范围小，分布密集度低，无法满足现有地基红外辐射测量系统天文标定的需要。根据系统的探测波段考察并选取IRAS、2MASS、WISE、AKARI 4个全空域巡天计划及其生成的红外星表。综合考虑大气弥散、大气衰减的影响，分析计算系统在短波红外1~3μm、中波红外3~5μm、长波红外8~10μm的极限探测能力及在对应点源星表中的最低可探测的星等。搜索选取可供系统观测的恒星，结果显示在短波选取4599个恒星目标，中波选取125个恒星目标，长波选取1个恒星目标，为我国现有地基红外辐射测量系统天文标定及红外星表进一步应用提供理论依据。The known infrared catalog has limited available quantity, limited coverage of waveband and irradiance, low intensity distribution. This can not meet the need for astronomy calibration of existing ground-based infrared radiation measurement system. According to the system detection waveband, IRAS, WISE, 2MASS, AKARI four all sky surveys and their infrared star catalogs were selected. Considering the impact of atmospheric dispersion and attenuation, the limiting detection capability of system in 1-3μm, 3-5 μm, 8-10 μm and the limiting magnitude in corresponding point source catalog was calculated. Searching in catalogs and selected stars which can be observed by system, results show that 4 599 stars in 1-3μm, 125 stars in 3-5μm, 1 stars in 8-10μm were found. This work also provides a theoretical basis for astronomical calibration and infrared star catalog application for domestic ground-based infrared radiation measurement system.
