摘　　要：针对制导弹药的弹道可视化仿真中,观察视角单一,场景搭建简陋,无法模拟战场环境下制导弹药在攻击中的动态过程等问题,提出一种制导弹药弹道可视化模型的搭建方法;以某型激光制导弹药为对象,基于Simulink与Unity3D软件建立了联合仿真模型,采用Matlab/Simulink软件构建六自由度弹道仿真模型,采用Unity3D搭建包括制导弹药、目标和战场环境在内的三维场景,采用UDP通信协议将Simulink中的仿真数据传输到Unity3D中,提出一种数值可视化技术,能同时观察制导弹药的飞行姿态和仿真数值结果,实现制导弹药在战场环境下的弹道可视化仿真;将制导弹药参数加载到仿真模型中,对不同状态的目标进行了模拟攻击实验,实验结果显示,该仿真模型能够多视角、全方位地显示制导弹药的飞行姿态、弹道和过载情况,对于需要修改参数以逼近实战条件下的攻击过程,每次修正都能立刻通过可视化平台查看和验证修改结果;该可视化仿真模型为制导弹药的可视化仿真提供了便利的方法,对制导弹药的设计和作战使用具有一定的参考作用。In the visual simulation of guided munitions trajectory,the observation Angle is relatively single,the scene construction is relatively simple,unable to simulate the dynamic process of guided munitions in the battlefield environment,a visual model of guided munition trajectory is proposed.Taking a certain type of Laser-guided munition as the object,establishes a co-simulation model based on Simulink and Unity3D software,uses Matlab/Simulink software to build a 6-DOF ballistic simulation model,uses Unity3D to build a three-dimensional scene including guided munition,target and battlefield environment.Using UDP communication protocol,simulation data in Simulink was transmitted to Unity3D,and a numerical visualization technology was proposed,which could simultaneously observe the flight attitude and simulation numerical results of guided munitions,and realize the visual simulation of ballistic trajectory of guided munitions in the battlefield environment.The parameters of the guided ammunition are loaded into the simulation model,and the simulated attack experiments are carried out on targets with different states.The experimental results show that the simulation model can display the flight attitude,trajectory and overload of the guided ammunition from multiple perspectives and in all directions.With each correction,the results can be immediately viewed and verified through the visual platform.The visual simulation model provides a convenient method for visual simulation of guided munitions,and has a certain reference role for the design and operational use of guided munitions.
