Feasibility Study of Small Antenna Aperture of Airborne Satellite High Date Rate Transmission Systems by Multiple Antenna and Multi-carrier Signal Processing

Air-born satellite high data rate transmission systems can realize quick response broadband real-time information transmission of large scale maneuver. The systems also play important roles on ocean exploration and mapping, marine resources research, remote monitoring, locating and rescuing marine disasters and safeguarding marine rights. Due to the small EIRP of the satellite and the performance limitations of the traditional signal transmission technologies, the air-born satellite antenna aperture of the high data rate transmission system is still relatively large and the small fixed-wing aircraft cannot realize high data rate satellite transmission. This paper analyzed the possible technical approaches to reduce the airborne antenna aperture. We proved that multiple antenna and multi-carrier signal processing which are physical layer transmission technologies can greatly reduce the airborne antenna aperture.
