Research and Implementation on Visual Simulation of Reelectro-optical countermeasure Based onVega

To evaluate the jamming effect of semi-active laser-guided missile induced by laser,this paper introduces a method,which is based on Visual C++ and MultiGen Vega environment to develop a virtual reality simulation system.The simulation models of the missile,the target attacked and the terrain are established with MultiGen Creator.Simulation models are driven by MultiGen Vega on the basis of mathematical models,models describe the processes of the semi-active laser-guided missile attacking the target and the laser jamming the missile seeker.Special effects are added to simulation,and the image of the target in the missile seeker is dis-played timely during simulation with openGL.The parameters of simulation system can be easily modified,and the simulation results are shown directly,these make the effects evaluation of weapons easily.
