摘要
隐身涂料在红外隐身技术的研究中占据重要位置。从涂料的隐身机理出发,以目标与背景的辐射对比度小于0.02作为红外隐身的评判标准,提出了一种关于涂料红外隐身技术的新的研究方向,并结合红外探测系统作用距离检验了这个评价标准。研究发现,考虑目标红外隐身时,不能盲目降低目标表面发射率。当辐射对比度减小到0.02时,作用距离比原先降低了71.4%。
Camouflage coating plays an important role in the study of infrared stealth technology. Based on the infrared stealth mechanism, a new study orientation is put forward for the infrared camouflage coating technology with the judgment criterion of infrared stealth, in which the radiation contrast between target and background should be less than 0,02. Lock-on range of detector system was also used to check this criterion. The results show that it is not suitable to only reduce the emissivity of target when considering infrared stealth of target. On the basis of the radiation energy difference between the target and background, the camouflage coating with proper emissivity can be chosen for target by taking specific combat environment into consideration. It is also found that as the contrast diminishes to 0.02, the lock-on range reduces by 71.4%.
