| The two most typical combat modes in modern war are air raid and air defense.Therefore,it is very important to improve the penetration ability of air combat forces and the air defense ability of ground forces.At present,there are some disadvantages in combat confrontation drill,such as high risk coefficient,high cost consumption and so on.Therefore,using computer simulation technology to simulate the attack and defense confrontation scene has become a hot research topic.This paper studies the space attack and defense countermeasure system,establishes the simulation model of the space attack and defense countermeasure system,and designs the overall framework of the system.The system framework includes the implementation logic and operation flow of the simulation system.Finally,a 3D visualization simulation system is built.On the basis of this framework,this paper mainly completes the following four aspects.(1)A variety of weapon systems including attack vehicle,radar,satellite,data link and command center are modeled and integrated in the simulation system.Each weapon unit module contains a universal interface for data interaction with the front end.(2)The optimization method of aircraft shape parameters based on particle swarm optimization is designed.An optimization model with lift to drag ratio and radar cross section(RCS)as optimization objectives is constructed.The particle swarm optimization algorithm is used to optimize the model,and the performance of the algorithm is verified by an example.The rationality and effectiveness of the optimization model are verified by the electromagnetic simulation software FEKO.(3)A fire distribution model based on genetic algorithm is designed.An optimization model with the threat evaluation function as the optimization target is constructed.The effectiveness of the optimization model is verified by an example.(4)The 3D visualization simulation system of virtual battlefield is constructed.The system uses a unified call interface to integrate various weapon modules,and combines with the open source cesium library to realize visual display.The simulation deduction system designed in this paper can show the actual attack defense confrontation scene more intuitively,which is conducive to the experimental data analysis and decision-maker to make a better operation plan.In addition,it improves the efficiency of human-computer interaction.The simulation system designed in this paper provides an effective deduction platform for both sides.The system has high generality and strong intuition.It solves the problems of high cost and high risk coefficient in actual confrontation training,and has high military application value. |
