英文摘要： According to the requirements of multi-band and shared-aperture in the next generation satellite platform, it is necessary to carry on the researches on the fundamental theory, basic framework, system modeling and other key techniques for the satellite RF integration system with the goals of reducing the antenna number and system cost, improving the reconfigurability, interchangeability, extensibility and the electromagnetic compatibility of the system. The open structure optimization for the satellite RF integration system, the low mutual coupling design for the satellite antenna integration, the arrangement optimization for the array elements, the reconfigurable design for the RF module interconnection, and the electromagnetic compatibility will be stressed in this project. The main contents include the design of satellite RF integration framework, the integrations of multi-band and shared-aperture satellite antenna and RF transceiver circuit, and the development of satellite RF integration experimental system. This project is an advanced topic in the new technique field of satellite electronic system design. It has a specific and urgent application demand because this research can provide a solid theoretical and technical foundation for the design and application of the next generation RF system on satellites, aircrafts, ships, and vehicles platforms.
