摘　　要：文章介绍了宽带短波(WBHF)信道研究的发展历程,根据ITS信道建模的方法,在对信道衰落特征及其噪声干扰统计特性进行分析的基础上建立了适当模型,并设定了特定环境下信道衰落模型及其噪声模型的相关参数。最后通过计算机仿真与实测数据加以比较,从散射函数能量分布、噪声时/频域电平以及噪声电平交叉率(LCR)方面验证了信道模型的合理性。This paper describes the development of research on wideband high frequency （WBHF） channel, the establishment of a proper channel model based on the analysis of fading characteristics and noise data of natural channel, in accordance with ITS channel modeling method, and the assumption the related parameters of channel fading model and its noise model in special conditions. Finally by comparison of the simulation with measured data, the rationality of the model is proved in aspects of the energy distribution of scattering function, the time/frequency domain level of channel noise and the noise level crossing rate（LCR）.
