Simulation of Early Warning and Detection Capability of Ballistic Missile in Boosting Phase Based on Infrared Characteristic

Aiming at the main infrared radiation characteristics of ballistic missile in boosting phase,this paper analyzes the structure,shape,size and lasting time of exhaust plume and the influence of atmospheric on infrared detection;according to the maximum operating range model and signal-to-noise ratio(SNR)of early warning satellite detector,simulates the technical and tactic index of early warning satellite combining with the given parameter,gives the method to improve the detection capability of ballistic missile.
