文中研究了红外对抗试验中黑体模拟真实目标温度和面积的设定过程。首先提出黑体能够有效模拟真实目标红外辐射特性所需遵守的两个原则：辐射照度相等和立体角相等；其次，依据红外理论推导了计算黑体温度的公式；最后，以歼-7飞机(J7)作为真实目标，仿真其在不同观测角下的红外辐射特性，并且加入大气透过率和路径辐射亮度对其红外辐射特性的影响，研究了不同观测角、不同导引头与目标距离下黑体的设定温度和面积。结果表明：在两个原则都满足的情况下，黑体设定温度的变化趋势与目标辐射亮度一致，而黑体设定面积的变化趋势与目标的投影面积一致。文中的研究成果可为开展红外制导武器对抗试验提供理论依据和数据参考。

The temperature and area of blackbody were researched for simulating the real target in the experiments of infrared countermeasure. First of all, the two principles that should be observed were proposed to effectively simulate infrared radiation characteristic of real object: equality of irradiance and solid angle. The formula which calculates the temperature of blackbody was secondly deduced based on the infrared theories. At last, Jian-7 plane was taken as real target; its infrared radiation characteristic was computed in the different viewing angle, the influence of atmospheric transmittance and path radiation luminance were also taken into account. The temperature and area of blackbody were studied in different viewing angle and distance of the seeker and target. The results show that the variable trend of blackbody′s temperature agrees with that of target′s radiation luminance and the variable trend of blackbody′s area agrees with that of target′s projected area under the two principles. The research fruit can provide theoretical basis and data reference for carrying out the countermeasure experiment of infrared guided weapon.
