摘要
针对战术弹道导弹（TBM）中段的弹道特性,建立了TBM在中段的温度计算模型和红外辐射计算模型。在红外辐射的大气传输理论基础上,综合考虑大气吸收和散射因素,分析了大气衰减对红外辐射的影响,得到了大气衰减作用下的目标辐射模型。在此基础上,建立了红外导引头对目标的探测距离计算模型;最后,在假定的仿真条件下,利用模型计算得到采用3-5μm和8-12μm双频段的红外导引头对中段TBM目标的作用距离为810 km,该结论可为反导拦截弹的设计提供数据支持。
According to the trajectory traits of tactical ballistic missile （TBM） in midcourse flight, the temperature model and the infrared radiation model of the TBM target are established. On the basis of the theory of atmospheric transmission of the infrared radiation, considering factors such as atmospheric absorption and scattering,the influence of atmospheric attenuation on infrared radiation is analyzed, and the atmospheric transmittance model is established, as well as the target radiation model under the influence of atmospheric attenuation. Then a model for calculating the detection distance of an infrared homing head upon a TBM is established. Finally,based on an assumed simulation condition, the proposed model is used and resut is obtained that the detection distance of an infrared homing head of two kinds of band,3 -51μm and 8 - 12μm for the midcourse TBM is 810 km. The conclusion can provide data support for the design of anti- TBM intercept missile.
