摘　　要：红外目标模拟器应当定期进行辐值校准。可以用多种方法校准,主要有光谱辐射计和专用的校准系统。采用辐射计定标后对红外目标模拟器校准,能够在现场进行,具有方便快捷的特点。专门研制的红外目标模拟器校准系统采用了辐射对比的方法,稳定可靠溯源性强。在8μm～14μm的光谱区间,10-10W/cm2/μm的量级上,给出了使用SR 5000红外光谱辐射计和校准系统两种方法的测量结果,并就测试中的一些问题进行了分析。Spectroradiometry of IRtargetsimulators(IRTS) should be calibrated to the standard regularly. There are two ways to calibrate IRTS, one is using IR spectroradiometer and other the IRTS calibration system. Blackbodies are the standard sources for both methods. The former has advantages of convenience and is fit for calibration in situ. The latter is a large instrument and suits for using in lab. By contrasting the collimating radiation, from IRTS and from standard, the calibration system can trace to standard directly. Results of the two methods are showing in the spectrum range 8μm to 14μm and in the order of 10-10W/cm2/μm, and analyses to the calibrations are given too.
