| 摘 要： | 在电磁环境仿真中，电磁辐射源的辐射范围的计算是仿真的重要部分。丈中提出了一种基于数字高程模型DEM（Digital Elevation Model）的电磁波通视算法，在考虑电磁波直线传播的基础上根据电磁波的绕射理论对结果进行修正，并且定义了高差视域数组存储计算结果。数组在存储通视范围的同时，对非通视部分给出了接收指定电磁辐射源的接收机天线理论最小高度。最后对算法进行了验证。

| Abstract: | The calculation of electromagnetic wave radiation is an important part of electromagnetic environment simulation.An electromagnetic wave visibility algorithm based on DEM(digital elevation model) is proposed.First,the results of linear electromagnetic waves are calculated,and based on this step,the results are corrected according to electromagnetic wave diffraction theory.Then a height difference view shed array is defined for storage of the results.Both the visible area and the minimum theoretical height o... |
