基于星座网络的Ka波段星地信道建模研究

摘要

该文以某星座网络项目为背景,对Ka波段的星地通信链路进行了分析,仿真了不同天气环境,特别是降雨对信道损耗的影响,以及它们与天线仰角、工作频率等参数的关系。同时,探讨了Ka波段星地信道的平坦性,建立考虑了天气环境的Ka波段星地信道仿真模型,并对该模型的系统性能进行了仿真分析。%The background of this paper is a constellation project.In this paper,the loss of land satellite channel at Ka-band was analyzed and simulated with different weather conditions,particularly the rain-attenuation model,and their relationship with the antenn
