基于软件无线电的通信卫星柔性测试技术OA北大核心CSTPCD

In response to the problems of high degree of specialization,poor operability,low soft-ware compatibility,and high iteration and update cost in the ground payload testing system for the communication satellites,this paper proposes satellite flexible testing technology based on software defined radio.By leveraging the characteristics of software defined radio's support for high-level language programming and high flexibility,different communication satellites payload testing systems are unified into a common hardware platform in a software-customized manner,and general test equipment is designed to realize technical and economic integration of satellite payload testing.It has been tested and verified in actual satellite mobile communication payload and aviation surveillance payload.The testing equipment based on software defined radio meets the testing needs of communication satellites payloads and can provide reference for exploration and application of software defined radio technology in the field of satellite testing.
