摘　　要：针对目标的探测、识别以及目标红外特征的模拟,提出采用人工红外光源脉冲照射目标的方法。以目标红外辐射特性形成的机理为依据,建立人工红外光源脉冲照射目标的物理模型;确定氙灯为红外光源,建立了目标红外辐射的计算模型,并对红外光脉冲照射时目标的红外特性进行了仿真计算与分析。结果表明:人工红外光脉冲照射可以对目标红外特性进行调制,在相同条件下,光源照射功率越大,照射距离越近,调制的效果越好;垂直照射比平行照射效果好。As to detect, identify and simulate for infrared characteristic, a method which the targets are pulsed irradiation through artificial infrared illuminator is proposed. Based on targets^s infrared characteristic mechanism, the physical model which the targets pulsed irradiation through infrared illuminator is builded. Kr lamp is ensured, infrared radiation character algorithm model is builded. Targets^s infrared characteristic through infrared illuminator pulsed irradiation is simulation calculated and analyzed. The results show that modulation of ground targets＇s infrared characteristic irradiated through infrared illuminator pulsed irradiation is possibility, in the same condition, the effection of modulation is better with the greater power, the nearer distance and vertical direction.
