本文介绍了无线电系统解决方案的实施，评估和验证，能够直接对目标用户（波束成形）的主辐射瓣。综合硬件架构集成了：（1）发射子系统，（2）天线阵列子系统，（3）同步子系统，（4）接收子系统，（5）数据处理单元子系统。实现了两种波束形成算法：最小方差无失真响应和相移波束形成器。辐射系统的波束形成能力的评估方面的最大指向偏差的主瓣相对于目标用户所在的方向，第一次波束宽度，和天线增益。
This paper presents the implementation, evaluation and validation of a radio system solution able to direct the main radiated lobe towards a target user (beamforming). The comprehensive hardware architecture integrates: (1) the transmitting sub-system, (2) the antenna array sub-system, (3) the synchronization sub-system, (4) the receiving sub-system, and (5) the data processing unit sub-system. Two beamforming algorithms are implemented: Minimum Variance Distorsionless Response and Phase Shift beamformer. The radiant system beamforming capacity is evaluated in terms of maximum pointing deviation of the main lobe relative to the direction where the target user is positioned, First Null Beam Width, and antenna gain.
