摘　　要：无线信道的特性直接关系到为实现优质可靠地超短波电台通信必须采用的技术措施,因此分析研究无线信道模型对于超短波电台通信有着重要的意义。针对平坦开阔地形的超短波无线信道进行了研究,介绍了无线信道的特性以及多径衰落的信道模型和统计特征,描述了超短波无线信道模型的组成框架,结合应用实际进行了信道仿真与性能分析,得到信道模型的时域和频域特性,仿真结果表明该模型满足应用需求,可以应用于超短波电台的算法设计仿真。As the wireless channel characteristics could influence UHF radio communication,the research on channel model is important to UHF radio. The UHF band channel characteristics of flat wide terrain are described and multipath fading statistical properties are introduced. Then simulation structure of channel model is proposed to get characteristics of time and frequency domain. Combining with application,channel model simulation is made. The result demonstrates that the model could meet the requirement and be applied to algorithm simulation of UHF radio.
