针对临近空间高动态飞行器容易受到空间干扰影响，导致通信质量下降甚至中断的问题，详细分析了临近空间高动态传输信道所受的三种主要干扰：雨衰、多径、黑障，并进行综合建模，重点研究了黑障的衰减特性和建模方法。同时，针对该信道特征提出了一种临近空间高动态飞行器上下行通信系统模型，仿真结果表明，该通信系统模型满足临近空间高动态飞行器通信传输要求，验证了模型方案的有效性，为未来临近空间高动态飞行器通信技术提供了一个全新的理论参考。

Near-space high dynamic vehicles are susceptible to spatial interference, which lower the quality of the communi-cation system. The three main spatial interferences, rain attenuation, multipath and blackout, are analyzed and comprehen-sively modeled. The attenuation characteristics and the modeling method of blackout are studied in detail. Furthermore, a down the line communication system for near-space high dynamic vehicles is proposed based on the channel characteristics. Simulation results reveal that the communication system meets the transmission requirement of the near-space high dynamic vehicles. The presented communication scheme is effective and provides a theoretical reference for the design of commu-nication system for future near-space high dynamic vehicles.
