摘要：

提出了一种分频段电磁环境绘制算法. 以雷达设备的电磁辐射功率密度表征电磁环境,计算数据时不区分频段,获得所有频段联合作用的数据场,根据雷达设备的分布及作用情况将数据场划分为对应不同频段的子区域. 使用光线投射算法绘制电磁环境数据场,在设计传递函数时生成多频段颜色查找表,以颜色区分频段,并绘制数据场. 在所有颜色查找表中保持前部若干颜色相同,绘制所有频段的联合分布. 最后,使用统一计算设备架构加速实现了实时分频段绘制. 实验结果表明,绘制结果显示了电磁环境中的频段分布信息,又反映了所有频段的联合作用情况,方便用户直观理解电磁环境.

Abstract:

A band rendering method for electromagnetic environment was presented. The electromagnetic environment is represented by electromagnetic radiation power density of radars, when the data band computing is carried, a volumetric data for all bands is got. The volumetric data was then divided into sub-regions for each band based on each radar effect. Ray casting algorithm was used to render electromagnetic environment in which the transfer function was expressed as a set of color lookup tables for each band, different band has different color. Among all color lookup tables, there are some same colors for rendering the combined effects of all bands. A real-time rendering method was carried out using compute unified device architecture. Experiments show that the rendering images can display the distribution of bands and the combined effects of all bands for electromagnetic environment, and are helpful for understanding the electromagnetic environment intuitively.

Key words: electromagnetic environment, band rendering, ray casting, transfer function design, compute unified device architecture
