摘　　要：本文分析了再入目标的红外辐射特性及主要影响因素认为：表征再入目标辐射强弱的物理量主要为再入目标的表面温度、表面积和发射率；表征再入目标材料红外辐射能力的物理量为辐射率（发射率）。进而探讨了高红外发射率材料，认为：几种化合物混合烧结后可在一段连续波段提高材料的红外发射率。The infrared radiation characteristics of reentry objective and the main influnce factors have been analysed in ths pape. It is considered tha the infrared-radiating intensity of a reentry objective can be chnaterital by its surface temperature, surface area and radiative ability. And the infrared radiating capaity of materials can be chaseterized by radiance. According to our recent reserch results on some high infrared radiance mateals, the infrared radiance could be improved over a certain continuous frequency range after mixing and sintering several compounds.
