| 摘 要： | 针对共形球面天线阵列,采用有向天线阵元,在保持阵列孔径不变的条件下,以阵元分布位置作为优化变量,以降低最大相对旁瓣电平为优化目标,运用改进的遗传算法对阵列进行稀疏优化,仿真结果表明:该方法能够降低球形阵列的旁瓣电平,达到了减少阵元个数、降低天线系统成本的目的。

| Abstract: | Improved genetic algorithm is adopted to thin spherical antenna array with directional elements under the condition of keeping array aperture.It takes elements distribution as optimized parameters,and reduces the maximum relative sidelobe level(MSLL)as an optimization objective.Simulation results show that this method can effectively reduce sidelobe level of spherical array and achieve the goal of reducing the number of elements and cutting the cost of antenna system. |
