Research On Missile Flight Trajectory Simulation And Tracking Technology Based On Vega Prime/Creator

Missile combat plays an important military position in Modern science and technology warfare, missile development in the pre-test simulation is necessary for the high development costs of missiles. Visual Simulation (Scene Simulation) technology plays a decisive role in the computer simulation technology, this technology has a certain practical significance in modern military field. The main purpose of this paper is to missile force analysis under normal circumstances. Then observing and controlling the flight path of the missile.In order to make the missile flight simulation more realistic, it is necessary to simulate the 3D environment of the missile. Therefore, the three-dimensional environmental simulation of missile flight needs to pay attention to the actual terrain 3D model making.The source of terrain data three-dimensional modeling terrain is usually derived from the USGS USGS DEM format or NIMA format DTED. The data in these two formats are hard to find on the Internet. Therefore, this paper uses Creator itself as a source of terrain data for the research objectives. In order to make the 3D terrain model made more realistic, this paper proposes a method of terrain texture display based on. Finally, on the basis of these algorithms, a local scene visual scene is established based on Creator.Next,the model will be built into the Prime Vega, to complete the visual simulation. In this thesis, the monitoring of the trajectory, in order to facilitate the missile real-time monitoring is needed to set up multiple windows in Vega Prime to achieve on the missile flight trajectory different position and angle monitoring. Traditional missile flight trajectory control method is generally by setting missile flight trajectory points in Vega Prime Pathtool tools, set up after the completion of the missile will complete the fixed orbit flight according to the locus of points. Although by this method can also realize the missile fixed trajectory, but the missile in flight simulation process after pre-set trajectory point will appear stop card phenomenon, and ultimately affect the fidelity of missile flight. In order to overcome this problem, the powerful matlab mathematical calculation ability by analyzing the force of missile, missile's six degree of freedom dynamic mathematical model is established, missile in flight trajectory is determined according to the initial position of the missile so as to completely avoid the process simulation of Caton. In order to ensure the trajectory of correctness by using MATLAB Simulink to establish the Simulink model of the missile, set a two output ports is location of the missile flight trajectory, another is the missile attack angle changes in the missile attitude. The last question is how to establish the mathematical model and finally applied to achieve the final 3D simulation of missile. The completed the final simulation is the main interface using VC + + powerful features, the Vega Prime window embedded into the MFC controls on the control display to complete, in order to complete the control of the missile trajectory. Will missile's six degree of freedom mathematical model in matlab program according to the functions of the package, through the MATLAB compiler will convert it into the form of dynamic link library loaded directly into the VS 2005 program and missile visual simulation in the VS 2005 platform on the final show.
