摘要: 该文研究了一种综合正六边形阵列天线方向图的新方法。通过选择多个初始点来抑制非线性最小二乘法局部收敛的缺点，有效地实现了阵列天线的全局优化。根据阵列单元轴向对称分布的特点，通过计算部分单元获得整个阵列天线单元间的散射系数矩阵，降低了互耦的影响。计算结果说明阵列方向图在最小二乘意义上逼近了预先设定的目标方向图。Abstract: This paper investigates a new method for synthesis of the hexagonal antenna array. The local convergence of the nonlinear least-square method is restricted by selecting several initial values, such can achieve the global optimization of the antenna array. According to the elements symmetry distributed in axis, the scattering coeffecient of whole antenna array can be achieved by calculating part of elements, and abase the influence by mutual coupling . Simulation results show the pattern of antenna array approaches the objective pattern in the least square sense.
