红外探测是弹道导弹预警的主要手段之一。分析了弹道导弹及其背景的红外辐射特性;在综合考虑地球曲率、高度、气象条件、大气特性等条件的基础上,建立了红外传输的空间大气透过率计算模型;给出了机载红外预警系统的探测距离模型及其求解方法;通过仿真分析了不同飞行高度的机载红外预警系统对不同射程弹道导弹的助推段、末助推段、中段、末段以及短程弹道导弹的预警能力。仿真结果验证了大气透过率计算模型的有效性,论证了机载红外预警系统执行弹道导弹预警任务的可行性。研究结果表明:处于特定高度的机载红外预警系统具有很强的战术弹道导弹预警能力。
Infrared detection is one of the main means of ballistic missile warning. The characteristics of the infrared radiation of the ballistic missile and its background are analyzed. Based on the comprehensive consideration of the conditions such as the curvature of the earth, the altitude, the meteorological conditions and the atmospheric characteristics, the calculation model of the space atmospheric transmittance of the infrared transmission is established. The early warning system detection range model and its solution method; through simulation analysis of the different flight altitude early warning system of airborne infrared range of different range of the ballistic missile boosters, the end of the thrust segment, the middle, the last paragraph and short-range ballistic missiles early warning capabilities . The simulation results verify the effectiveness of the model for calculating the atmospheric transmittance and demonstrate the feasibility of early warning of airborne infrared systems on ballistic missiles. The results show that the airborne infrared warning system at a certain altitude has a very good tactical ballistic missile warning capability.
