摘　　要：以人工红外光源照射车辆的物理模型为基础，综合考虑自然环境与人工红外光源对车辆的影响，建立起车辆表面温度的计算模型和红外辐射计算模型。在分析以氙灯为红外光源的光谱特性基础上，对某车辆照射时表面温度进行了计算与测量，在此基础上，对某车辆在3～5舯和8～14μm波段的红外辐射进行了仿真计算与分析。结果表明：红外光照时车辆的红外特性将发生改变，改变的程度取决于光源的照射功率、照射时间、照射距离以及光源的入射角。Based on the physical model of the vehicle which irradiated through artificial infrared illuminator, the normal circumstance and artificial infrared illuminator are combined to affect vehicle. The calculation model of surface temperature and infrared radiation character is built. Analysis of spectra characteristic based on Xe infrared illuminator, taking the vehicle for example, vehicle＇ s surface temperature irradiated through infrared illuminator are calculated and measured. On the basis of calculation of the temperature, 3 - 5μm and 8 - 14μm wave-band＇ s infrared radiation is calculated and analyzed. The results show that the effection of vehicle＇ s infrared characteristic irradiated through infrared illuminator are determined by illumination＇ s power, time, distance and illuminator＇ s incident angle.
