Modeling and simulation analysis for the antimissile-warning-ability of the airborne IR early warning system

Infrared surveillance is one of the main means for antimissile warning. Firstly, the characteristics of infrared radiating of ballistic missile and its background were analyzed. Taking into account of telluric curvature, altitude, meteorologic condition, atmosphere characteristic and so on, the three dimensional atmospheric transmittance model of infrared transfer was set up;the detecting distance model of the airborne IR early warning (AIREW) and its solution were given;then the antimissile-warning-ability of AIREW in different altitude in the boosting phase, the end-boosting phase, the midst-phase, the end-phase of ballistic missile and the short-haul ballistic missile were analyzed through simulation. The simulation results validate the effectivity of atmospheric transmittance model and demonstrate the feasibility of the AIREW in performing the antimissile warning mission. The conclusion indicates that the early warning ability of the tactics ballistic missile is strong for the AIRREW in given altitude.
