| 摘要: |
| 采用热像仪记录伪装网样品不同时段的热图，分析了日照对伪装网热迷彩的影响。伪装网的热迷彩效果受装饰布太阳能吸收率影响非常大，甚至可以抵消或超过发射率差值因素。实验采用的伪装网深绿装饰布太阳能吸收率较高，热红外发射率比土黄装饰布低0.11以内时，在日照下深绿斑块辐射温度与土黄斑块接近或超过土黄斑块；深绿装饰布热红外发射率比土黄低0.27时，可保证在夏季的强日照下深绿斑块辐射温度低于土黄斑块，且有较大差值。 |

| Abstract: |
| The thermal IR images of camouflage net were recorded at different time in a day. The influence of sunshine on IR pattern of the camouflage net was discussed. The solar energy absorptivity of the camouflage cloth of the nets influences the IR pattern under sunshine greatly, and the influence even exceeds that of thermal IR emissivity. The dark green cloth of camouflage net, whose thermal IR emissivity is lower than that of khaki cloth, absorbs more solar energy. When the emissivity difference between khaki cloth and dark green cloth is less than 0.11, the apparent temperature of dark green cloth may be equal to or higher than that of khaki cloth in the sunshine. When the emissivity difference between khaki cloth and dark green cloth reaches 0.27, the apparent temperature of dark green cloth is lower than that of khaki cloth in the burning summer sunlight. |
