洞库口部的水雾热红外伪装性能分析

Analysis on Thermal IR Camouflage Performance of Water Fog at Cavern Mouth

洞库口部与背景的红外辐射差异是红外热成像仪探测洞库口部的基础。介绍了人工水雾及其红外伪装原理,同时,将水雾设备作用于实际洞库口部。通过红外热成像仪采集数据,测试和比较了水雾开启前和开启1,2 min时洞库口部的红外热图,并结合红外图像信息处理软件进行定线温度分析。结果表明:人工水雾在洞库口部的红外伪装方面起到了很好的遮蔽效果。

The difference of infrared radiation between cavern mouth and its background is the elements of the cavern mouth detected by the IR thermal imager. The artificial water fog is prepared by the water fog system that is installed in the actual hole, and its IR camouflage principle is introduced. Based on the scheme design, the data of IR radiation are acquired by the thermal imager. The thermal images of cavern mouth before opening water fog system are tested and compared with these images obteined when opening the system 1 minute and 2 minutes, respectively, and then applied to the alignment temperature analysis by the infrared image information processing software. The results show that the better performance of artificial water fog is proved through the comparison of the thermal image and temperature curve.
