【摘要】:為了利用垂直維度的空域資源進行三維波束賦形,提高終端接收信號的信干噪比和系統(tǒng)容量以及系統(tǒng)能量效率,實現(xiàn)綠色節(jié)能的通信,對均勻平面陣列天線的三維波束賦形技術(shù)的基本原理進行了研究.波束在垂直方向的角度分辨率直接影響著垂直維度的空域資源利用率,通過Matlab仿真分析了不同因素對垂直方向角度分辨率的影響.仿真結(jié)果表明,水平角度對垂直方向的角度分辨率基本沒有影響,隨著俯仰角的增大,均勻平面陣在垂直方向的角度分辨率明顯降低,但可以通過增加陣元的數(shù)目提高垂直方向的角度分辨率,實現(xiàn)對特定目標方向有效的三維波束賦形.
[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.
