摘　　要：研究人工红外光源对地面目标红外特性的影响,对目标的探测、识别、红外特征的模拟有重要的意义。建立了人工红外光源照射目标的理论模型,对影响目标表面温度的各种因素进行了分析,重点讨论了人工光源对目标表面温度的影响。以合肥某建筑物为例,对红外光源照射时的目标表面温度进行了计算与测量,在此基础上对目标红外辐射进行了计算与分析。结果表明:人工红外光源照射目标时,目标红外特性的影响主要取决于人工光源的照射功率、照射时间、照射距离以及入射角。Study on contrast of ground targets and backgrounds irradiated through artificial infrared illuminator has a great significance to detect,identify,track,simulate for target infrared characteristic.The theory model which the ground targets were irradiated through artificial infrared illuminator was built.All the factors effecting on target surface temperature were analyzed.Artificial illuminator effect on surface temperature was mainly discussed.Taking a building in Hefei for example,target surface temperatures irradiated through infrared illuminator were calculated and measured.On the basis of the calculation of the temperature,the infrared radiation was calculated and analyzed.The results show that the effect on targets infrared characteristic irradiated through infrared illuminator are determined by the illumination power,time,distance and illuminator incident angle.
