摘　　要：红外系统的探测距离除了受探测器本身系统的制约之外,还受到目标辐射、背景辐射和大气传输等因素的影响。针对红外系统接收的弹丸相对辐射,提出一种新的红外系统探测距离计算模型,该模型考虑了红外系统接收弹丸辐射的等效面积辐射、弹丸周围一定范围内的等效背景辐射和大气对弹丸辐射的衰减换算。在飞行弹丸表面辐射计算的基础上,推导出新的红外系统对弹丸的探测距离计算方程,并对其进行仿真分析。The detection range of infrared system depends on its dynamic characteristic, the radiation of target and background, the atmospheric attenuation and so on. Aimed at the flying projectile＇ s relative radiation received by the infrared system, a new detection range model of infrared system was proposed. It considered the equivalent area radiation of the projectile and the equivalent background radiation a- round the projectile and atmospheric attenuation. Based on analysis of infrared radiation on the surface of projectile, a new calculation equation for detection range was derived and analyzed.
