为弥补二维平面内弹道仿真的缺陷,体现三维仿真多视角动态演示的优越性。以比例导引法为例对弹道进行仿真,在MATLAB/Simulink环境下建立三维弹道的仿真模型,采用虚拟现实建模语言VRML(virtual-realitymodelinglanguage)建立三维虚拟场景,并通过Simulink接口将仿真模型导入,实现了对三维导引弹道的可视化仿真,形象地演示了导弹从发射到击中目标的整个过程,并且目标的运动轨迹可以实时控制,可以从不同角度观察导弹的飞行状态,更好的实现了对导引规律的仿真。

In order to counteract the defect of two-dimensional simulation and embody the advantage of three-dimensional simulation, taking the proportional guidance law as an example, the three-dimensional simulation model was established based on MATLAB/Simulink, the virtual-reality modeling language(VRML) was applied to establish the three-dimensional visual scene and with the Simulink to get the result of guidance equations. The whole flight process form different angles was demonstrated, and the guidance law can be completed much better.
