摘要
提出了一种基于地形信息的平流层通信系统传播损耗预测算法 ,给出了预测算法的计算机实现 ,并且对平流层通信传播损耗与地形关系的仿真结果进行了分析。
A propagation loss prediction algorithm of stratospheric communication system based on topographic information is presented in this paper. The program of the algorithm aided by computer is described. And the relation of the propagation and the topographic information is analyzed. The research in this paper has great significance on the performance simulation of stratospheric communication system for which no measurements are available.
