The Calculation of the Tank Surface Temperature Fieldbased on the Solar Radiation Model

目标表面温度场的建立是红外仿真的基础。根据红外成像仿真的基本流程,分析了影响坦克表面温度场的主要因素,建立了太阳辐射模型,并引入云遮系数法修正该模型,定量计算了太阳辐射对坦克温度场的影响;综合坦克内热源,履带摩擦产生的热能和风速等方面影响,得到计算坦克温度场的数学模型。该模型能实时计算坦克表面温度,对坦克的红外成像仿真工作有一定参考价值。

The target surface temperature field is the basis of infrared simulation. According to the basic process of infrared imaging simulation, the paper has analysis the main factors affecting the tank surface temperature field , established solar radiation model and the introduction of cloud cover coefficient method to fix the model, the model quantitative calculation of solar radiation on the temperature field; consolidated tank heat source , track the heat generated by friction and wind speed impact, get the calculation of the mathematical model of the tank temperature field. The model can calculate the surface temperature of the tanks in real-time. Tank infrared imaging simulation work has a certain reference value.
