【摘要】：導彈作為當代尖端武器,可對敵方的軍事設施實施精確、毀滅性的攻擊。因此受到各國軍方的重視。想形成戰(zhàn)斗力需要進行大量的操作訓練,使每名操作號手熟練操作并能很好的協(xié)同。同時需要定期對導彈武器進行維護保養(yǎng)和系統(tǒng)測試,但由于導彈武器系統(tǒng)的體積龐大、結構復雜,特別是某些敏感電子元件的壽命和可靠性有一定使用次數(shù)的限制,不可能頻繁進行通電操作。本文將虛擬現(xiàn)實技術應用到軍事領域,實現(xiàn)了導彈飛行視景仿真系統(tǒng)設計,刻畫了導彈從發(fā)射、飛行到擊毀目標的全過程,本系統(tǒng)既可以對導彈設備的系統(tǒng)狀態(tài)進行測試,以確保導彈武器系統(tǒng)保持良好的作戰(zhàn)性能,也可以為部隊實行操作訓練的常態(tài)化提供一定的幫助。本文主要工作如下:(1)導彈彈道的解算與仿真是導彈飛行視景仿真系統(tǒng)的關鍵環(huán)節(jié),根據(jù)導彈和目標艦船的相對運動關系建立彈目坐標系,在小擾動線性化的條件下,得到簡化的俯仰通道導彈運動方程組,建立導彈俯仰通道的制導控制系統(tǒng)模型,對導彈彈道進行解算,并通過仿真進行驗證。(2)深入研究目前先進的三維建模技術,運用DOF技術、紋理貼圖技術、細節(jié)層次技術,使用Creator建模軟件完成導彈武器系統(tǒng)和目標艦船三維模型的構建;利用高程數(shù)據(jù)和衛(wèi)星圖像制作大地形場景,通過外部引用技術、模型封裝等技術對模型進行優(yōu)化,以提高系統(tǒng)運行的流暢性。(3)在VegaPrime視窗中采用多通道技術,達到同時觀察導彈和目標運動;為提高視景仿真系統(tǒng)畫面的真實感,采用粒子系統(tǒng)制作場景特效,具體包括雨、雪、云層等環(huán)境特效、導彈尾跡效果和擊中目標后的爆炸效果,為這些特效分別設定專屬的觸發(fā)開關;運用BUMP方法,可以實現(xiàn)快速準確地判斷導彈與目標艦船之間碰撞出現(xiàn)與否。(4)以VS2005軟件作為系統(tǒng)程序開發(fā)平臺,Vega Prime視景仿真軟件作為場景動畫的渲染工具,MATLAB彈道解算程序作為導彈運動的驅動程序,使用通用的API數(shù)據(jù)接口將其連接,利用C++語言編寫系統(tǒng)驅動程序實現(xiàn)天氣切換、視角切換和場景切換功能,最終利用MFC生成可執(zhí)行程序,完成導彈飛行視景仿真系統(tǒng)的開發(fā)。
[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.
