摘　　要：根据目标红外辐射特性形成的机理,探讨了人工光源对目标红外特性调制的方法。通过建立人工光源照射目标的理论模型,对人工光源照射时目标的表面温度进行了仿真计算与实际测量,在此基础上对目标红外辐射进行了计算与分析。结果表明:人工光源可以对目标的红外特性进行调制,调制的效果取决于光源的照射功率、照射时间、照射距离及光源的入射角。一般情况下,夜晚照射时调制效果明显,白天照射时调制效果不明显。Based on the formation mechanison of targets infrared characteristic,this paper discusses a method to modulate ground targets＇s infrared characteristic through artificial illuminator.The theoretical model of ground targets irradiated artificial illuminator is established,then the targets surface temperature is calculated and measured,and the targets＇ infrared radiation is calculated and analyzed.The results show that the infrared characteristic of ground targets can be modulated through artificial illuminator,and the effect of modulation is determined by illumination power,time,distance,and incident angle.In general conditions,the effect of modulation is obvious at night,but not in the daytime.
