The infrared radiation of carbon dioxide at high temperature has been measured using this technology. We introduced the principium,flow field and the working gas of the high frequency plasma wind tunnel. The experiment condition, equipment, method of data processing and the analyse of the experiment results were introduced. We had measured the infrared radiation of carbon dioxide at four different temperatures between 1 500 and 3 000 K using this technology for measuring the radiation of high temperature gas which had been developed by ourselves. Measuring the spatial distribution of the infrared radiation of carbon dioxide using Able-transform were also introduced. We have analyzed the emission spectrum at 4.3 μm of carbon dioxide at high temperature. The conclusion had been obtained that the center wavelength of the emission spectrum moved to the long wave when the temperature risen. The authors also had analyzed and contrasted the experiment results and the data obtained from literatures.
