基于隐身效率的红外隐身性能评估方法

Evaluation Methods of Infrared Camouflage Performance Based on Camouflage Efficiency

为定量描述红外隐身材料性能,进而评价装备的红外隐身效果,从目标的红外辐射特性出发,结合热成像系统的视距估算理论及静态性能理论,提出了目标"隐身效率"的概念,在此基础上建立了红外隐身性能评估模型。对某装备在不同观测等级下和不同探测概率下的隐身效率进行了分析计算,从理论上模拟了红外探测系统对隐身装备的探测情况,实现了对装备隐身性能的定量评估。

In order to describe the performance of the infrared camouflage materials quantitatively and estimate the camouflage effect of the equipment, the concept of camouflage efficiency is introduced, and a estimation model is built, which starts from infrared characterization of target. In the model, we combine apparent distance estimation theory and static capability of thermal imaging system. Then the camouflage efficiency of a specific equipment is calculated according to different observation scale, which achieves a theoretical simulation, and verifies the validity of the estimation model.
