| 摘 要： | 基于粒子群优化算法提出了一种非均匀子阵波束形成方法。首先利用粒子群优化算法实现线阵最优非均匀划分；其次在线阵最优划分的基础上扩展到面阵最优非均匀划分；最后在面阵最优非均匀划分的基础上在期望区域内形成任意指向的波束。该方法既可以在期望区域内形成任意指向波束，又充分发挥了子阵级波束形成的优势。仿真结果表明该方法是有效的。 |

| Abstract: | To overcome cost and complexity for beamforming at the element level,a nonuniform subarray beamforming approach based on particle swarm optimization is proposed.Firstly,optimum subarrays of unequal sizes of a linear array is achieved.Secondly,the square array is divided into optimum subarrays of unequal sizes based on the first step.Finally,the beamforming in the desired direction is performed based on the above optimum subarrays.The new method can not only form beams in the desired direction,but also take ... |
