A Study Of The Antiaircraft Gun Drilling Simulation System Based On Virtual Battlefield

As modern war is becoming faster and military technology is developing quickly, using military drilling simulators/systems based on virtual battlefield environment to train soldiers and commanders is becoming an important way for military drilling. Based on the analysis and generalization of status quo of international and domestic research on military drilling simulators/systems, this thesis discussed key technologies in military drilling simulators/systems such as modeling technology, collision detection and generation of special effects.The main work stated in this thesis focused on following aspects:1. Based on the realization of terrain modeling and entity modeling, the kinematic modeling in military drilling simulation system was studied in depth and the kinematic models of antiaircraft gun and aircraft were design and constructed.2. Definition and classification of collision detection were introduced and collision response in military drilling system was discussed. Three problems in collision detection in the drilling system were studied: collision between shell and objects, model pickup and terrain matching. An optimized forecast strategy for collision was put forward to improve the efficiency of collision.3. The particle system technology which is used widely in generation of special effects was introduced, and the methods for generation of battlefield fire and smoke were studied and a particle system for simulating the tail fire of missile was put forward.4. An antiaircraft gun drilling simulation system, which can realize the counterwork in training, was designed to train gun operator and commander of antiaircraft gun company together.At last, the main work of this thesis was summarized and more research work that needs to be done was also brought forward.
