摘　　要：雷达频率作为虚拟战场雷达作战信息可视化的重要内容,是战场可视化研究的重点。传统的雷达频率表现,主要通过建立光与频率的映射关系,利用颜色来进行表现,这种以光磁物理映射关系的表现方式在大规模虚拟战场表现上容易造成混乱,不利于区分不同类型信息。利用粒子法,将粒子跳动的速率与频率进行关联,在保证物理特性关联度的前提下,解放了颜色表现方式,同时利用射线和透明度法将雷达传播路径和衰减强度信息也进行了表现。The frequency of radar, as the main content on virtual battle-field, is an important aspect about visualization of battle-field. The normal demonstration displays the frequency by color based on the mapping between color and frequency. This kind of demonstration may make confusion in the visualization of large battle-field. In this paper, frequency is associated with the speed of bouncing particles. This method could ensure the associativity of physical feature and liberate the manner of color. Meanwhile, the path of radar propagation and attenuation intensity were displayed in this paper.
