摘　　要：针对多星测控和高精度测量的需求,介绍了“半球面+柱面+全数字波束形成、收发一体的球形全空域多波束天线实现方案”的比较分析过程和实验验证结果。实验结果表明,采用该天线的测控系统能在实现多目标同时遥测遥控的同时大幅提高跟踪性能,测量精度与传统测控站相当,满足未来多星环境下全空域高可靠跟踪、高精度测量的要求。According to the demands of multi-satellite TT&C and high precision measurement,this paper introduces the analysis process and verification of the spherical array antenna design scheme featured by hemisphere+column array antenna+digital beamforming,and integration of receiving and transmitting.The results show that by adopting the spherical array antenna,simultaneous TT&C for multiple hemispherical targets can be achieved,and the tracking performance is improved greatly,and the measurement precision is equivalent to that of traditional TT&C station,so this TT&C system is capable of satisfying the requirements of hemispherical high reliability tracking and high precision measurement demands for future multi-satellite environment.
