Modeling and Simulation of the Dynamical Infrared Radiation of Ballistic Missile in Boost Phase

With development of the Missile technology, there are more and more challenges for the technology of early-warning satellite detection. The early-warning satellite can compute the data of launch point and impact point of a missile by detecting the changing infrared radiation of the missile. Therefore, the research on the infrared radiation of ballistic missile in boost phase is important for developing the detecting technology of early-warning satellite. In this paper, the dynamical infrared radiation model has been constructed based on the characteristics of trajectory and infrared radiation of a ballistic missile in boost phase, and the model has been verified by simulation based on the data of a two stage ballistic missile.
