【摘要】：导弹作为当代尖端武器,可对敌方的军事设施实施精确、毁灭性的攻击。因此受到各国军方的重视。想形成战斗力需要进行大量的操作训练,使每名操作号手熟练操作并能很好的协同。同时需要定期对导弹武器进行维护保养和系统测试,但由于导弹武器系统的体积庞大、结构复杂,特别是某些敏感电子元件的寿命和可靠性有一定使用次数的限制,不可能频繁进行通电操作。本文将虚拟现实技术应用到军事领域,实现了导弹飞行视景仿真系统设计,刻画了导弹从发射、飞行到击毁目标的全过程,本系统既可以对导弹设备的系统状态进行测试,以确保导弹武器系统保持良好的作战性能,也可以为部队实行操作训练的常态化提供一定的帮助。本文主要工作如下:(1)导弹弹道的解算与仿真是导弹飞行视景仿真系统的关键环节,根据导弹和目标舰船的相对运动关系建立弹目坐标系,在小扰动线性化的条件下,得到简化的俯仰通道导弹运动方程组,建立导弹俯仰通道的制导控制系统模型,对导弹弹道进行解算,并通过仿真进行验证。(2)深入研究目前先进的三维建模技术,运用DOF技术、纹理贴图技术、细节层次技术,使用Creator建模软件完成导弹武器系统和目标舰船三维模型的构建;利用高程数据和卫星图像制作大地形场景,通过外部引用技术、模型封装等技术对模型进行优化,以提高系统运行的流畅性。(3)在VegaPrime视窗中采用多通道技术,达到同时观察导弹和目标运动;为提高视景仿真系统画面的真实感,采用粒子系统制作场景特效,具体包括雨、雪、云层等环境特效、导弹尾迹效果和击中目标后的爆炸效果,为这些特效分别设定专属的触发开关;运用BUMP方法,可以实现快速准确地判断导弹与目标舰船之间碰撞出现与否。(4)以VS2005软件作为系统程序开发平台,Vega Prime视景仿真软件作为场景动画的渲染工具,MATLAB弹道解算程序作为导弹运动的驱动程序,使用通用的API数据接口将其连接,利用C++语言编写系统驱动程序实现天气切换、视角切换和场景切换功能,最终利用MFC生成可执行程序,完成导弹飞行视景仿真系统的开发。
[Abstract]:As a modern sophisticated weapon, missiles can carry out accurate and destructive attacks on enemy military installations. As a result, the military attention of all countries. In order to form combat effectiveness, a large number of operational training is needed, so that each operator can operate skillfully and cooperate well. At the same time, there is a need for regular maintenance and systematic testing of missile weapons. However, due to the large size and complex structure of missile weapon systems, in particular, the lifetime and reliability of certain sensitive electronic components are limited by a certain number of times of use. Power-on operations are not possible frequently. In this paper, the virtual reality technology is applied to the military field, the design of missile flight scene simulation system is realized, and the whole process of missile from launching, flying to destroying target is described. The system can not only test the system state of missile equipment, but also can test the system state of missile equipment. In order to ensure the missile weapon system to maintain good combat performance, it can also provide some help for the regular operation training of troops. The main work of this paper is as follows: (1) the calculation and simulation of missile trajectory is the key link of missile flight scene simulation system. According to the relative motion relation between missile and target ship, the project-target coordinate system is established, and under the condition of small disturbance linearization, The simplified kinematic equations of the pitching channel missile are obtained, and the guidance and control system model of the pitch channel of the missile is established, and the missile trajectory is solved and verified by simulation. (2) the advanced 3D modeling technology is deeply studied. The 3D model of missile weapon system and target ship is constructed by using DOF technology, texture mapping technology, detail level technology and Creator modeling software. Using elevation data and satellite images to make large terrain scene, optimizing the model through external reference technology, model encapsulation and other techniques, in order to improve the smooth running of the system. (3) using multi-channel technology in VegaPrime window, Achieving simultaneous observation of missile and target movements; In order to improve the reality of the scene simulation system, the particle system is used to make the scene special effects, including the environmental effects such as rain, snow and clouds, the missile wake effect and the explosion effect after hitting the target. For these special effects to set up a separate exclusive trigger switch; By using BUMP method, the collision between missile and target ship can be judged quickly and accurately. (4) the VS2005 software is used as the system programming platform, Vega Prime visual simulation software as the rendering tool of scene animation. The MATLAB trajectory program is used as the driving program of missile motion, which is connected by the general API data interface, and the system driver is written in C language to realize the functions of weather switching, angle switching and scene switching. Finally, the executable program is generated by MFC, and the missile flight scene simulation system is developed.
