Abstract

Abstract: In the near space communications system，the rainfall，atmosphere，flash will cause the open space link channel quality deterioration.In this paper，the Ka-band communication channel near space wave propagation characteristics is analyzed，and Ka-band near space channel model is established.To analyze the changes in elevation rain in the open space link failure on the signal fading effects of elevation are calculated under different circumstances related parameters，and the near space channel model is simulated by the model accuracy for the analysis of near space link provides a platform for future research.

Key words: near space, elevation angle, channel modeling, simulation

摘要： 在临近空间通信系统中，降雨、大气、闪烁等都会引起空地链路信道质量的恶化。通过分析Ka波段临近空间通信信道的电波传播特性，建立了Ka波段临近空间静止通信信道模型。分析了空地链路中仰角变化时，降雨对信号衰落的影响，估算了不同仰角下的相关参数值，并对不同仰角下Ka波段临近空间静止信道性能进行仿真，验证了模型的正确性，为临近空间链路分析及后续研究工作提供了平台。
