文章围绕机场终端区域电磁环境的建模与三维呈现绘制方法两方面内容展开研究,从电磁波空间传播模型的建立方法入手,研究了统计经验法如何建立电波传播模型,以及物理手段建立电波传播模型的算法。在空间传播模型建立的基础上,又研究了对电磁环境整体和细节的呈现算法。最后对典型的导航设备的电磁信号进行了三维呈现。
This paper focuses on the two aspects of the modeling and 3D rendering of the electromagnetic environment in the terminal area of the airport. Starting with the establishment of the electromagnetic wave propagation model, this paper studies how the statistical experience method establishes the radio propagation model and the physical means to establish the radio propagation model algorithm. Based on the establishment of the space propagation model, the algorithm of presenting the whole and details of electromagnetic environment is also studied. Finally, the three-dimensional representation of the electromagnetic signal of a typical navigation device is presented.
