摘　　要：红外系统捕获飞行弹丸时,必须保证该系统对飞行弹丸的作用距离大于弹丸到红外系统的距离,分析了传统的红外系统作用距离计算公式,考虑了弹丸在飞行过程中与红外系统之间的距离会随着飞行时间变化,而红外辐射在大气中的衰减随着波长和传输距离不同而变化,因此红外系统接收到的弹丸辐射会在弹丸飞行过程中随着时间而变化;同时考虑到弹丸在飞行中系统接收的红外辐射受天空背景影响和弹丸截面等效面积的辐射影响,从而重新提出了红外系统的作用距离模型。在简单弹道模型的基础上,计算并分析理论飞行距离与系统作用距离相互影响的关系,获得红外系统对弹丸发射过程捕获的最佳位置,为红外系统探测飞行弹丸的地点选取提供理论依据。Infrared system, whose operating range must be greater than the range between the projectile and the infrared system, was used to capture the projectile in flight. In this paper, the traditional operating range formula was analyzed. The impact radiation of the infrared system received attenuation factors would be changed over time of the projectile flight, because the range between the projectile and the system would be changed over time of the projectile flight and the radiation attenuation during the atmospheric transmission changed with wavelength and the transmission distance. Considering the equivalent area radiation and background radiation were a new model of the operating range calculation of infrared system for projectile in flight was proposed. Simulating the change curve of projectile flight path and operating range, based on the simplified ballistic trajectory model of projectile, the optimum region to capture the projectile in flight was calculated, it provides theoretical basis for selection of the locations for the system to capture the projectile.
