Security Systems, Air Defense Training Of Dis-based Air Situation

With background of an antiaircraft training system,simulation models of many kinds of cruise missile and warplane are established,including physical model,decision-making model and three-dimensional model. Based on mission planning technique and Distributed Interactive Simulation (DIS),a virtual drone simulation system that has novel applications is developed. The simulation system is a computer generated forces (CGF) system,and it can provide virtual air-raid forces as enemy for antiaircraft forces in antiaircraft training. Three-dimensional visualization of simulation process is realized in the system.Firstly,this paper analyzes the function and project requirement that should be achieved,and puts forward overall architecture of the virtual drone simulation system.Secondly the object-oriented modeling method is researched in the paper,accordingly simulative physical models of virtual drone based on object-oriented technique and modularizing structure are established. The physical models include model of dynamics and kinematics,model of radar electromagnetic wave reflection,model of infrared radiation,model of detection system,model of weapon system and model of combat evaluation.Then this paper briefly introduces the mission planning system of cruise missile,analyzes the characteristic of intelligent decision modeling in virtual battlefield. Considering the simulation of warplane,this paper puts forward agent-based method of intelligent decision modeling which meets the demand of military simulation. Therefore a multi-agent system (MAS) can be established to deal with collaboration and cooperation in team.Finally,two key technology of system are described:data management based on database and Visualization. In addition,a simulation instance is provided which simulates assaulting course of cruise missile.
