Space vehicles are subjected to significant aerodynamic heating during reentry into the Earth's atmosphere. In recent years, silicon-based materials have attracted attention as innovative thermal protection materials, and this laboratory has focused on silicon carbide and systematically conducted heating experiments using high-temperature air plasmajets. In this study, the heating behavior of silicon carbide was observed spatially and temporally using a wide dynamic range camera. In particular, we paid attention to the weak radiation around the test piece and investigated the spatial and temporal distributions of the radiation and the mechanism leading to the radiation.
