Modeling and Simulation of Guidance and Control System of Air-Borne Kinetic Energy Interceptor

To study the guidance and control system of air-borne kinetic energy interceptor （KEI）, the engagement process for boost phase ballistic missile interception is explored, and the trajectory model of a ballistic missile during the boost phase is established. According to the boost phase flight characteristics of ballistic missile, the guidance and control system models of KEI are constructed, including the structural model, the dynamic and kinetic model, the relative movement model, the measurement model, the compound guidance model and the direct force/aerodynamic force control model. Under the environment of Matlab/Simulink, the digital simulation system is developed. The simulation results prove the fea- sibility and practicability of the model.
