摘　　要：实现对临近空间飞行器的测控通信则是实现情报收集、侦察监视、通信中继、对空对地作战等领域的广泛应用的重要基础之一。针对Ka波段临近空间飞行器测控通信链路的信道特征,建立了包括降雨衰减、多径衰落和阴影遮蔽等因素的完整信道模型。通过仿真证明了建模的合理性和正确性,结果可作为临近空间技术的理论参考模型。One of the fundamental conditions for near space vehicles practical application in the broad application prospects for near space vehicles, such as information collection, reconnaissance-and- surveillance, communication relay and to-air or to-ground strike, near space vehicles is TT＆C （Tracking Telemetering and Command ） communication support. In view of channel characteristics of TT＆C communication links of Ka-band near space vehicles, rain attenuation, multi-path fading effect were taken into consideration to establish a complete channel model. The rationality of the model were proved by simulations, and the results can be used as theory reference space technology. and shadowing and correctness models in near
