The Design And Implementation Of Defensive Tactical And Offensive Combat System Based On HLA

With the development of science and technology and the improvement of modern information technology in military, complex virtual battlefield environment and tactical combat process based on more efficient simulation in virtual reality are ways of modern military training to make soldiers adapt to the operational environment quickly and to improve the response of war. Simulation of offensive tactical and offensive combat provides a virtual battlefield environment and tactical command by the use of computer simulation, visual computing, multimedia and graphics technology, based on field combat and information warfare of force modernization. As the main means of combat simulation in peacetime and tactical training, simulation field with high sense of reality has become one of important researches for military modernization. Based on the model of tactical training and data of simulated battlefield, focusing on creating complex battlefield environment, tactical exercises and maneuvers assessment models, this paper designed and realized training of information and large-scale virtual battlefield with manual intervention. Meanwhile, combined with completed tactical changes, communication of information battlefield and special effects of combat, it will ultimately build a simulation platform with high sense of realitv.In this paper, high level architecture HLA (High Level Architecture) is used to design the system architecture in order to promote interoperability and reusability between simulation systems. HLA High Level Architecture is a common architecture for distributed systems and has become a standard for distributed simulation systems. The design of HLA took full advantage of object-oriented approach and a variety of design patterns, and standardized the description of the object model through the object model template OMT (Object Model Template). Design of system's object model is the base of achieving HLA distributed interactive simulation. HLA required object model to describe the interactive data between the federate and federal members during the execution of federate by object model. Systems based on high level architecture can communicate between different systems. To ensure synchronization between systems and reliability of communication, the transmission between the simulation systems can be unified by runtime infrastructure RTI (Run-Time Infrastructure). In this paper, the BH RTI is a platform for distributed interactive simulation researched and developed by Beijing University of Aeronautics independently. Through the feature package of RTI bottom interface, the workload of programming on bottom interface is greatly reduced and the functions of managing federal members fast and effectively and developing of system are realized. Combined with current popular simulation software Multigen-Paradigm Vega and the Creator, through rapid development technology of Vega simulation platform and rapid modeling technology of large-scale terrain of Creator, with configuration of specific tactical battlefield environment, the graphics modeling module of defensive tactical and offensive combat system is designed.Through the entire design and development process of defensive tactical and offensive combat system, the paper summed up the general rapid development process of distributed simulation system of military defensive tactical and offensive combat, and provided scientific and effective methods for the application of virtual reality in the defensive tactical and offensive combat system. This paper focused on the process of designing system architecture by HLA combined with the platform of Vega. On the basis of the application, combined with features of modern warfare, a virtual military confrontation platform is created the training and practice of effective tactical command. Through the record playback and damage statistics, the reasonability of tactical is evaluated and the tactical level and command capability of participants are improved. And practical problems are solved and design methods are summarized in the process of design and development in order to provide a theoretical basis and empirical support for virtual reality technology in battle applications.
