Abstract：In the present paper, the abilities of resistance to random error of the two non-source temperature calibration methods put forward previously were researched by adding random error of different sizes to blackbody radiant flux to simulate different precisions of the multi-spectral high temperature measurement system. Experimental results show that the non-source calibration method based on cure similarity principle (NCCSP) has strong anti-random error ability and it is suitable for large random error system. When the random error is very small, its precision is lower than the non-source calibration method based on the MSP transfer function (NCCTF), but when the random error increases to a certain range, the NCCSP accuracy is much higher than the latter. The NCCTF in a certain random error range has a high calibration accuracy of the extrapolation, but its resistance to random error is weak and can be applied to the measurement system of small random error.
