摘　　要：当前对卫星移动通信的研究正逐步从UHF频段向L、S频段发展，而S频段的信道环境相对UHF和L频段的信道来说更加复杂和恶劣。本文在少量测量数据和Loo模型的基础上，采用高斯白噪声建立了S频段的卫星移动信道的数学模型，给出了在不同条件下模型参数的值。经计算机仿真证明文中模型的概率累计函数与实际信道相一致。模型的实现简单易行，具有一定的实用价值。The research on satellite mobile communication has developed from UHF band to L band and S band. The channel environment of S band is worse and more complex than that of UHF and L band. In this paper, an S band satellite mobile channel model has been estab- lished using Gaussian White Noise based on the Loo model and a few measurement data, the parameters of this model under different conditions are also given. It is shown by com- puter simulation that the CDF of the model is in accordance with that of the real channel. The method has practical value which is easy to realize.
