摘　　要：研究地面目标的红外立体特征,有助于全面掌握目标红外特性的细节,对红外热像的模拟、红外目标识别以及红外隐身设计等都有着重要的意义。文中通过对影响目标温度因素的定量分析,建立了地面目标表面温度的一般数学模型。以一维导热微分方程为例,计算了某建筑物墙壁不同方位的外表面温度在一天中随时间的变化关系,并与实际测量值进行了比较。在此基础上,最后对建筑物的红外辐射进行了理论计算和讨论。结果表明地面目标的红外立体特征在白天非常显著,在晚上的立体特征则没有白天显著。The research of the infrared stereo feature of ground target is useful for describing the detail of infrared feature, and it plays an important role in the field of infrared image simulation,infrared target recognition and controlling the target infrared radiation to realize infrared camouflage and so on. In this paper, the various factors that influence the target surface temperature were analyzed, then the model for the calculation of target surface temperature was introduced. The relation between temperature and time for some building wall outside surface by daylight was calculated using one dimension heat conduction differential equation. It proves that the calculation method is correct according to the comparison between the result value and the measured value. On the basis of the calculation of temperature, the infrared radiation was calculated and discussed. The result shows that the infrared stereo feature of ground target is more obvious in day than in night.
