红外目标温度的高低影响着被发现的距离，隐身技术可以降低目标的表面温度。通过分析目标温度、红外辐射、光电探测等之间的关系，建立了目标温度与被发现距离的数学模型，通过仿真计算，给出了几种典型红外目标温度变化对被发现距离影响的结果，可为隐身技术手段的运用提供参考。

Different temperatures of infrared target can influence the detection distance, and the surface temperature can be reduced by stealth technologies. A mathematical model of target temperature and detection distance was put forward by an analysis of the relationship of target temperature, infrared radiation and photoelectric detection. Based on the simulation calculation, the results of the effect of several typical infrared targets temperature variation on detection distance were presented, which are useful in the application of stealth technology.
