The limited effort in this paper is focused on studying the infrared radiation performance of Ammonium Perchlorate/ hydroxy-terminated polybutadiene(AP/HTPB) and Magnesium/ Teflon(MTV) agents, in order to compare the differences in the spectral distribution of the two agents at different doses and tube shell sizes. A FTIR remote-sensing spectrometer was used to characterize combustion flame radiation products and a Spectraline SC7000 imaging spectrometer was used to test the radiation performance of each band. The test results show that the radiation energy of AP/HTPB agents is 5-8 times smaller than that of MTV agents under the same conditions. In addition, as the mass is small (5g), the spectral distribution of AP/HTPB agent θα / β / λ . is 0.6:1:0.15, which is better than MTV agent whose θα / β / λ . is 2.3:1:0.15. But as the mass increased to 40g and the diameter of the tube shell increased to 40mm, the mass burning rate of the MTV agent increased from 0.287g/s to 4.167g/s, and the mass burning rate of AP/HTPB agent increased from 0.258g/s to 2.920g/s. At this time, the MTV spectral distribution did not change much, but the radiation energy of AP/HTPB agents is changed more concentrated in the near-infrared band, and the spectral distribution θα / β / λ . becomes 1.4:1:0.3.
