The results of the experiments demonstrate that the uncertainty of BRDC,which is based on the high accuracy cryogenic radiometry system,is much higher than that of the traditional radiation calibration which is based on the standard radiation source.

• 实验结果表明基于标准探测器的反射比定标法由于采用了直接由高精度低温绝对辐射计传递的标准探测器,与传统的基于辐射源传递相比其测量精度得到有效提高,并且受现场大气条件的影响小。
