摘　　要：传统的多波束卫星系统多为固定资源分配方式,缺乏足够的灵活性。跳波束通过时间分片技术满足了用户的非均匀、动态业务需求,提高了卫星的资源利用率和业务服务能力,但目前跳波束技术在卫星中的应用面临着许多挑战。文章从系统和技术层面进行了分析与思考,指出了跳波束系统中存在的难点问题,并梳理分析了其关键技术。最后结合人工智能等新兴技术给出了跳波束系统的发展趋势,为我国后续卫星跳波束技术的应用发展提供了思路。The resources of traditional multi-beam satellite systems are mostly fixed allocated and lack sufficient flexibility.The beam hopping technology meets the dynamic and unbalanced requirements of users through time division multiplexing,and improves the resource utilization and service capabilities of the system.However,the application of beam hopping technology in satellites faces many challenges.From the system and technology level,this paper study and analyzes the beam hopping systems.Specifically,the difficult problems and key technologies of beam hopping systems are analyzed.Finally,combined with the new technologies such as artificial intelligence,the development trend of the beam hopping system is given,which provides the idea for application development of the beam hopping technology in satellite.
