研究了在不同温度下发射率为0.605～0.935的红外迷彩涂层的表观温度和红外图像以及由高、中、低3种发射率涂料组成的三色红外迷彩的辐射对比度随温度变化情况,获得了三色红外迷彩涂料的适用温度范围。结果表明:对于三色红外迷彩涂料,目标与背景实际温差每升高1 K,辐射对比度|C|增大约0.011,即伪装效能随温差增大而降低;当温差超过±20 K时,三色红外迷彩涂层的平均表观温度与背景表观温度之差大于10 K,即涂层几乎没有红外伪装效能。
The apparent temperature and infrared images of the infrared camouflage coatings with different emissivities from 0.605 to 0.935 at different temperatures and the variation of the radiation contrast of the three-color infrared camouflage with high, medium and low emissivity coatings with temperature were studied. Access to the three-color infrared camouflage paint temperature range. The results show that for the three-color infrared camouflage paint, the actual temperature difference between the target and the background increases by 1 K and the radiation contrast ratio | C | increases by about 0.011, that is, the disguise efficiency decreases with increasing temperature difference. When the temperature difference exceeds ± 20 K, The difference between the average apparent temperature of the infrared camouflage coating and the apparent temperature of the background is greater than 10 K, ie, the coating has almost no infrared camouflage efficacy.
