空—空通信信道的统计特征分析

Analysis of the statistical characteristics of the air-to-air communication channel

近年来空—空通信技术受到了高度关注,空—空信道建模与分析是空—空通信领域的研究热点之一。文章依据德国宇航局基于实测数据的空—空信道统计模型,通过仿真实验分析了地面场景切换时路径接收信号的统计分布特征,其实验结果对空-空信道建模具有一定的参考价值。

In recent years, air-to-air communication technology has been highly concerned, and the air-to-air channel modeling and analysis is one of the research hotspots in the field of air-to-air communication. Based on the statistical air-to-air channel model according to the measurements of the German Aerospace Center, the statistical distribution characteristics of path received signal are analyzed by the simulation experiment when the ground scene changes, and the results have a certain reference value for the modeling of the air-to-air channel.
