摘要
研究雷达电磁波问题,对复杂电磁环境可视化是目前计算机图形学领域的热点。为图形实时改变和交互,采用雷达天线方向图函数和科学计算可视化领域中绘制等值面的方法,在DirectX9.0c环境下实现雷达电磁波面在三维空间的效果显示。通过在matlab环境下仿真试验表明,所生成的雷达电磁波面效果符合雷达天线方向图所描述的波束形态,经过剪枝优化等操作后,场景显示效果流畅,可用于教学、训练,虚拟战场场景,为受训人员提供直观、动态画面,提高训练效果。
Visualization of complex electromagnetic environment is a difficult and hot spot in the field of Computer Graphics.Radar antenna pattern function and the method which applied in the area of visualization in scientific computing are the main way which we used for drawing isosurface,and we draw radar＇s isosurface with DirectX9.0c.The result show that the effect of radar＇s isosurface meets the radar antenna pattern function.Through optimizing,such as pruning,the scene is smooth enough for teaching and training.The effect of the radar＇s isosurface can be not only applied in teaching,but also used in the training system which has the Virtual Battlefield Scene,to help trainees to promote their achievement by offering the intuitional and dynamic scene.
