摘　　要：射频带宽增加导致的阵列天线波形相位不一致会造成宽带波束成形指向角度误差,从而影响通信质量。文中针对传统均匀划分带宽存在的无法提供多种宽度的带宽的问题,提出了一种非均匀带宽划分算法,通过优化理论实现了带宽宽度的多样性。仿真表明,在提供多样性带宽的同时,能够保持与均匀划分相近的性能。The inconsistent phase waveforms of the array antenna caused by the increase of the RF bandwidth causes the error of wideband beamforming pointing angle,thus affecting the communication quality. This paper proposes a non-uniform bandwidth partitioning algorithm based on the problem that the traditional uniform bandwidth allocation cannot provide multiple bandwidths. The diversity of bandwidth width is achieved through the optimization theory. The simulations show that while providing diversity bandwidth,it is possible to maintain similar performance with even division.
