摘要

本文提出了一种新的简化的纯相天线阵波束形成方法，该方法主要是针对最佳波束形成时，过对称后相量的奇对称特征构造。由于相量的奇对称特性结构，使纯相天线阵的实际自由度减小了一半。通过适当的矩阵变换和数学分析，得到了权重的纯相位梯度向量和Hessian矩阵。采用纯相位共轭梯度算法和牛顿算法得到了最优的数值相量。仿真结果表明，该方法可以有效地消除干扰，但大大降低了计算复杂度。

Simplified beamforming on phase-only arrays

In this paper, a novel, simplified beamforming on phase-only antenna arrays is presented, which stemmed from the odd symmetric characteristic construction of phasor after persymmetry when optimum beamforming. By the odd symmetric characteristic construction of phasor, the actual freedom of phase-only antenna arrays was lessened by half. The phase-only gradient vector and Hessian matrix of the weight were formulated by using some proper matrix transforms and mathematical analysis. The optimal numerical phasor was obtained by phase-only conjugate gradient algorithm and Newton algorithm. The simulations demonstrated that the new approach can null interferences efficiently, but with dramatic reduced computational complexity.
