According to the characteristic of hf channel , the watterson model which was ccir recommended was made 首先从短波信道的特性分析入手，建立了基于ccir建议的watterson模型的短波信道模型。

We discuss the characteristic of wireless channel and hf " s at the forepart of the paper and , analysis several typical model about hf channel , and consider the math representation and statistic characterization , after that we select watterson hf channel model as the simulated model in this paper 在论文开始我们讨论了无线通信信道的传播特性和高频信道的传播特性，分析了高频信道的数学表述和统计特性，最后我们选择了watterson高频通信模型作为本论文的仿真和模拟模型。
