摘　　要：阐述了红外侦察告警设备作用距离等效折算的重要性及常见方法,推导了不同气象条件下基于飞机目标表观辐射亮度、目标背景表观辐射亮度差的红外辐射等效折算公式,并对其中的假设近似进行了修正计算。通过折算表明:折算后的图像与参考实测图像从灰度分布与变化趋势一致性上符合较好,证明了提出的红外辐射等效折算方法的合理性。The significance and method of equivalent calculation on warning distance of IR search ＆ warning equipment is introduced. Equivalent infrared radiate computative formula based on apparent luminance of plane target, difference between target and background luminance under different atmosphere mode is presented, and the hypothesis in the course of calculating is corrected. The result shows computative image from atmosphere mode 1（atmosphere mode of test） is approaching about gray-distributing and disciplinarian with image of atmosphere mode 2（atmosphere mode to be computative）. The result indicates that the method of equivalent infrared radiate calculation is rational.
