For the problem of analysis of transmission characteristics of satellite communication wireless channel for military mobile user objective system, this paper uses statistical model analysis method to study it. Based on the research of the UHF frequency band and the Ka frequency band communication links of MUOS system, the propagation characteristics of the channel propagation loss and multipath fading are analyzed. It shows that the UHF band wireless channel is a complex time-varying feature. Its propagation characteristics are greatly affected by the physical environment and scene of the mobile terminal. Ka band compared with the UHF band, its propagation characteristics are mainly affected by the atmospheric effects, and the rain attenuation effect is the most significant, these characteristics have an important influence on the transmission capacity of MUOS system.
