为了能够快速达到了解目标红外辐射特性的目的,可以通过建立目标的热红外辐射特性理论计算模型,并分析影响目标红外辐射特性的因素,最终得到目标的红外辐射特性的仿真计算的数学模型。借助野外试验,利用自动气象站、辐射测温仪等仪器测量了一天24h的相关数据,并通过多次数值模拟不断对模型进行优化,最终得到较为准确的目标红外辐射特性仿真计算数学模型,为实现目标红外伪装的技术途径提供理论依据。

In order to quickly achieve the purpose of understanding the infrared radiation characteristics of the target,the theoretical calculation model of the thermal infrared radiation characteristics of the target can be established,and the factors affecting the infrared radiation characteristics of the target can be analyzed,and finally a mathematical model for the simulation calculation of the infrared radiation characteristics of the target can be obtained.With the help of field experiments,we used automatic weather stations,radiation thermometers and other instruments to measure the relevant data 24 hours a day,and continuously optimized the model through multiple numerical simulations,and finally obtained a more accurate mathematical model of the target infrared radiation characteristics simulation calculation.Provide a theoretical basis for the realization of the target infrared camouflage technical approach.
