雷达作用范围与波束的可视化仿真是虚拟战场态势展现的关键.通过研究雷达电磁波传播的特点,提出了一种新的外围轮廓线提取算法,不但解决了轮廓线单值问题还准确表现了外围盲区;在波束三维表现方面,通过建立简单的空间任一方向图函数,得到采样后不同剖面的传播衰减值,生成三维波束体.

The simulation and visualization of radar range and beam are the key in virtual battlefield. This paper presents a new extraction of peripheral contour line based on related theories. Not only can the single value of contour line be solved, but also peripheral dead zone can emerge obviously. In the aspect of 3D by establishment of pattern function of arbitrary point, after sam-pling, the propagation attenuation of different section planes can be gotten and the 3D beam can be generated. The final results of experiment behave well.
