This paper describes time-frozen measurements using a CCD camera system for total radiation behind strong shock wave in a shock tube. The measurements are carried out for the shock velocity range from 6.8km/s to 12.5km/ s at the initial pressure range from 13.33Pa to 133.3Pa in air. The experimental results are compared with the numerical ones. There is a relatively good agreement between the experimental and numerical results at 10km/s shock velocity at the initial pressure 13.33Pa, although some discrepancies appear at the other velocity range. It is found that the full width at half maximum of profile of the first-peak becomes narrower and the thickness of radiation front becomes broader, as the shock velocity increases at the lower initial pressure. At the higher initial pressure, there is a limitation of spatial resolution in the present experiment.
