Research On Attack-defense Confrontation Simulation Method For Missile Based On HLA

Now every country in the world puts a high value on the cruise missile’sdevelopment, as it becomes the dominant force in modern war. In the process ofdevelopment of cruise missile, simulation technology can be used to simulate thestrategy of attack-defense confrontation system for missile, improve the missile system,help system selection, test product performance and so on. This thesis focuses on theresearch of route planning technology in the attack-defense confrontation system formissile, establishment of the2D and3D simulation scenarios, and building structure ofdistributed system framework based on HLA. At the same time, the unmanned aerialvehicle (UAV), as an intelligent and information-based weapon, needs real-timemonitoring and remote control provided by the ground station’s navigation system.However,2D and3D simulation scenarios as well as HLA framework developed in thisthesis can complete the function of the navigation system of UAV ground station. Onthe other hand, route planning technology on the cruise missile is equally applicable toUAV. Therefore, this thesis realizes two kind of functionality in the same system. Themain work of the thesis is as follow:(1) At first, the thesis introduces the system’s overall structure and function, thenaccording to the different function of system, details the various modules’ structure andfunction in the system, they are: route planning algorithm module,2D map scenariomodule,3D ground and object scenario module, data and graphic display module, HLAcommunication architecture module.(2)Four route planning algorithms have been realized in this thesis: sparse A-Staralgorithm, sparse A-Star algorithm based on threat, genetic algorithm and hierarchicalalgorithm. In the thesis, the traditional route-path-cost formula has been improved andsparse A-Star algorithm based on threat is according to the basic method of sparseA-Star algorithm. Experiment results and analysis on the four algorithms are shown atthe last part of thesis.(3) Create2D and3D simulation scenarios with MapX and OpenGL technology.The2D simulation scenario provides the whole map display of China at different levels with using map display functions of MapX, and uses map tool program interface ofMapX to realize appropriate interactive operation. The3D simulation scenario realizesthe real3D terrain’s simulation which is based on real digital elevation data, andcombining with texture mapping, color rendering, fog and light simulation in OpenGL.This thesis uses the skybox technology to simulate sky environment. In addition, DeepExploration software can convert complex3D models into other files that can let3Dsimulation scenario import these3D models successfully.(4) Analyze the federal members’ hierarchy structure of the system and theinteractive relationship between the main entities and members according to the basicprinciple and structure of HLA, at last complete the distributed system framework basedon HLA.
