The ballistic missile tracking method using dynamic model

Ballistic missile tracking in time is one of the key technologies in the missile defence system. Aiming at problems about ballistic missile kinetic states real-time estimation, this paper investigated the method of ballistic missile tracking using dynamic model. Firstly, based on analyzing characteristics of ballistic missile´s motion, this paper builds dynamics model of ballistic missile under the condition of gravity turn model; Secondly, based on analyzing parameter of dynamic model, this paper builds simplified kinetic model of ballistic missile; Lastly, this paper analyses how to chose kinetic states variable, and then educes ballistic missile kinetic states function and simulates the method of real-time estimation based on EKF, the result shows that the proposed method can track the ballistic missile, what is more, the estimation precision is high.
