The Research And Implement Of Distributed Simulation Platform For Antiaircraft Artillery Training System

With the rapid developing of computer technology, the application of simulation technology reaches the high level. Recently, in the field of military, establishing the simulation platform of weapon system becomes a research hotspot.On the basis of realizing the fire-control real-time simulation system in the antiaircraft artillery weapon system, this paper designs and constructs the distributed weapon system numerical simulation platform based on Ethernet, which uses the simulation technique, network communication technique and virtual reality technique. The platform is used for researching and realizing the Antiaircraft Artillery Training Simulator. Also, it can be integrated with the actual equipment to construct semi-physical simulation system to make the theoretical validating experiment.First, the paper introduces the basic structure and functions, and expatiates the key points and difficult problems in the process of fire-control simulation, such as the filtering, the independence of the tracking LOS (line of sight). Second, this paper analyzes and studies the OpenGL graphics functions, and develops the scene simulation system with the scene simulation technique. For the contradiction between reality and real-time capability, this paper puts forward the solution to improve the efficiency of creating target, and realizes the real-time simulation of scene system. Then, this paper raises the general design of the simulation platform based on Ethernet and introduces the implementation principles of every subsystem in detail. Finally, this paper analyzes and studies tracking errors and shooting prediction which are calculated by the fire-control system, and brings forward the solutions for reducing errors by comparing with experimental curves and the tracking precision may be increased efficiently.
