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。
When the infrared system catches the flying projectile, it is necessary to ensure that the distance of the projectile to the flying projectile is larger than the distance between the projectile and the infrared system. The calculation formula of the distance of the traditional infrared system is analyzed, and the distance between the projectile and the infrared system Will change with the flight time, and the infrared radiation attenuation in the atmosphere with the wavelength and transmission distance varies, so the infrared radiation received by the projectile in the process of projectile flight over time; taking into account the projectile at The infrared radiation received by the system in flight is affected by the sky background and the radiation of the equivalent area of the projectile section, so that the distance model of the infrared system is resumed. Based on the simple ballistic model, the relationship between the theoretical flight distance and the system interaction distance is calculated and analyzed, and the best position captured by the infrared system for the projectile launching process is obtained. This provides a theoretical basis for the location selection of the projectile in the infrared system.
