The modeling of missile is complicated, its number of alternant information is larger. With the way of graphics and blocking in Simulink, Simulink models of missile movement module, rudder system module, guide and control module are made. The difficulty of modeling for the complicated dynamic system is solved. Adding the way of mobile changing orbit to attaching missile model, it not only validates abilities of attacking and defensing of missile, but also increases simulation effect of attackdefense counterwork.
