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。

Abstract: 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 around 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.
