| 摘要: |
| 跟踪与数据中继卫星系统（TDRSS）是转发地球站对低、中轨航天器的跟踪测控信号和中继从航天器发回地面的信息的卫星通信系统，自适应多波束形成是TDRSS中的一个关键技术。讨论了一种基于中频实数加权的LMS算法的自适应多波束形成方法，采用两路正交实信号进行实数加权，大大节约了硬件资源。理论分析及计算机仿真结果都证明了该算法的可行性及优越性。 |

| Abstract: |
| The tracking and data relay satellite system(TDRSS) is a satellite communication signal relay system which provides tracking and data acquisition services between low earth-orbiting spacecraft and ground control or data processing facilities,it can also relay the information sent by spacecraft.Adaptive multi-beam forming is a key technology of TDRSS.An adaptive multi-beam forming method based on intermediate frequency real number weighted LMS algorithm is presented in the paper.The hardware is used in an economic way for the real-number weight of two orthogonal signals.The algorithm is proved feasible and preponderant by theoretic analysis and computer simulation. |
