摘要
针对电磁波覆盖范围分析的研究现状,文章研究了计算和分析相对简便的等效地球半径法:介绍了等效地球半径的定义及确定方法,探讨了基于等效地球半径和地形的电磁波覆盖范围分析方法,并基于投影原理分析了等效地球与实际地球的投影,实现了电磁波覆盖范围的高效分析及结果的精确可视化。
Aiming at the current status of studying the coverage extent analysis of electromagnetic wave, the paper studied the effective earth＇s radius method to analyze the coverage extent of electromag- netic wave, and analyzed the map projection between effective earth and real earth. Finally, it realized the coverage extent analysis of electromagnetic wave and it＇s visualization.
