【摘要】：为了利用垂直维度的空域资源进行三维波束赋形,提高终端接收信号的信干噪比和系统容量以及系统能量效率,实现绿色节能的通信,对均匀平面阵列天线的三维波束赋形技术的基本原理进行了研究.波束在垂直方向的角度分辨率直接影响着垂直维度的空域资源利用率,通过Matlab仿真分析了不同因素对垂直方向角度分辨率的影响.仿真结果表明,水平角度对垂直方向的角度分辨率基本没有影响,随着俯仰角的增大,均匀平面阵在垂直方向的角度分辨率明显降低,但可以通过增加阵元的数目提高垂直方向的角度分辨率,实现对特定目标方向有效的三维波束赋形.
[Abstract]:In order to make use of the spatial space resources of vertical dimension to shape three-dimensional beam, to improve the signal-to-noise ratio, system capacity and system energy efficiency of the received signal, the communication of green energy saving can be realized. The basic principle of three-dimensional beamforming technique for uniform plane array antenna is studied. The angular resolution of the beam in the vertical direction directly affects the spatial resource utilization of the vertical dimension. The influence of different factors on the vertical angular resolution is analyzed by Matlab simulation. The simulation results show that the horizontal angle has no effect on the vertical angular resolution. With the increase of the pitch angle, the angular resolution of the uniform plane array decreases obviously in the vertical direction. But by increasing the number of array elements to improve the angular resolution of vertical direction, the three-dimensional beamforming can be realized effectively in the specific target direction.
