Research into the Trajectory Simulation Model of Ground to Air Missile

Ground to air missile trajectory simulation was an important tache in combat process simulation of ground to air missile fire unit.It affected the result of airraid-defense combat simulation,which was the rationality of simulation model,the feasibility of airthmetic and the validity of process description.The trajectory simulation model,arithmetic,trajectory simulation and key problem resolve method ware put forward in this paper,it was based on the need of fact.The feasibility,validity and practicability of model and arithmetic ware validated by practice application.
