The progress of the blackbody source emissivity measurement based on the controlling surrounding radiation is presented, including the principle, method and equipment. The theoretical model is established according to the Planck′s radiation law. The equipment is set up, and the blackbody emissivity results are analyzed and factors affecting the results are discussed. The measurement results of blackbody emissivity agree well with the theoretical modeling result, and the standard deviation of measurement results achieves 0.07%. It is shown that the temperature repetitiveness of the heated halo has little influence on the emissivity results by the proposed method. Similarly, the change of heated halo temperature has little effect on the results when the difference in temperature between heated halo and blackbody is large enough. The proposed method has potential applications in the blackbody emissivity measurement during the thermal infrared remote sensing facility on orbit. It also set an important base to raise the level of infrared remote sensing calibration on board.
