摘　　要：针对现有步兵战车反坦克导弹模拟训练器存在的弹道仿真不真实,战场环境不逼真的问题。依据三点法导引规律建立导弹的弹道模型,在MATLAB软件下实现弹道的数值仿真计算。构建步兵战车、三维地形和反坦克导弹的实体模型,以虚拟现实软件Vega作为核心图形引擎实现反坦克导弹攻击过程的视景仿真,使训练人员能够直观地观察导弹飞行状态及命中目标后的毁伤效果。采用多分辨率LOD地形分割算法对战场环境进行优化,在一定程度上解决了大规模地形在逼真度和仿真实时性上难以兼顾的问题。研究可为增强训练系统的逼真度提供一个切实可行的方法,对提高模拟器的训练效果具有重要的现实意义。Aiming at the problems that trajectory simulation and battlefield environment in training system for anti -tank missile of infantry Fighting Vehicle is not realistic, a missile trajectory model has been built based on three point method guidance trajectory, and numerical simulation was performed in MATLAB software. The infantry fighting vehicles, anti tank missiles and 3D entity model have been built. We used the virtual reality software Vega as the core graphics engine to realize the visual simulation of anti tank missile, so that the training personnel can directly ob- serve the missile flight state and damage effect. Multi resolution LOD terrain segmentation algorithm was used to opti- mize the battlefield environment, and the problem that the large scale terrain is difficult to balance on the fidelity and real-time simulation has been solved. It provides a feasible method for improving the fidelity of the training system, and also has great practical significance for improving the effect of training simulator.
