摘　　要：对虚拟战场环境中电磁信号的可视化技术进行了初步的研究,介绍了几种通信信号和干扰信号的时域和空间域的绘制方法。重点研究了利用圆台逼近波束绘制方法和逐点计算波束表面曲线采样点绘制方法,利用OpenGL函数实现对电磁信号的空间域的绘制,实现了通信过程中多径现象的可视化绘制,并将其嵌入到Vega搭建的虚拟战场环境中。最后本文对绘制效率进行了初步的探讨,并提出了绘制效率的改进方法。The visual technology of electromagnetic signal in the virtual battlefield environment was investigated and several description methods of signal in the time-field and space-field were introduced. Great emphases were put on description methods such as beam-riding approaching which was based on round iron and calculated the curve points on the surface of beam-riding point by point. The description of electromagnetic signal in the time-field and space-field was implemented by OpenGL, and the multi-pathway in the communication progress was described. The entire above was embedded in the virtual battlefield environment which was built by Vega. In the last, the efficiency of the above methods was discussed, and an improved description method was brought forward.
