从国军标的迷彩伪装技术指标出发,对兼容伪装技术要求(可见光-近红外和热红外波段)的热反射涂层的光谱技术指标进行研究。结果表明:为满足国军标对可见光-近红外的伪装要求,兼容伪装功能的热反射涂层反射率应限定上限值,以翠绿色涂层为例,热反射涂层太阳反射率≤41.8%,近红外反射率≤72.5%方可满足伪装技术要求;通过提高涂层的太阳反射率,有助于改善日照条件下涂层的热红外伪装效能以及放宽涂层低发射率的限定值,以翠绿色涂层为例,太阳反射率为35%的热反射涂层发射率可放宽到不超过0.72,太阳反射率为41.8%的热反射涂层发射率可放宽到不超过0.81。
Based on the national military standard camouflage camouflage technical indicators, the spectral specifications of the thermal reflective coatings that are compatible with the camouflage technology requirements (visible-near-infrared and thermal infrared) were studied. The results show that in order to meet the requirements of the national military standard for visible-near-infrared camouflage, the reflectance of the thermal reflective coating compatible with the camouflage function should be limited to the upper limit. Taking the emerald green coating as an example, the solar reflectance of the thermal reflective coating is ≤41.8 %, NIR reflectance≤72.5% to meet the requirements of camouflage technology. By improving the solar reflectance of the coating, it helps to improve the thermal infrared camouflage effect of the coating under the sunlight condition and relax the limited value of the coating low emissivity, Taking emerald coat as an example, the heat-reflective coating having a solar reflectance of 35% can be relaxed to not more than 0.72 and the heat-reflective coating having a solar reflectance of 41.8% can be relaxed to not more than 0.81.
