摘　　要：结合相关文献给出的实测数据,介绍了S波段地空信道的特性,建立了地空信道的离散时间等效基带模型,且分析了信道滤波器抽头系数的统计特性。文中提出的模型有助于地空通信系统的设计。Characteristics of the S-band air-ground channel with measured data given by related literature are presented. The discrete-time equivalent baseband model of the air-ground channel is established. The statistical properties of the channel filter tap coefficients are analyzed. The model can be acted as a guidance in the design of air-ground communication systems.
