摘　　要：针对制导武器共形相控阵天线阵列形成特定波束指向的方向图特性问题,讨论了几种共形天线阵列的配置方式。首先建立棱锥阵列和圆锥阵列的几何模型,再分别就棱锥阵列和圆锥阵列讨论天线单元的不同配置方式,并建立各自的天线方向图函数和方向性增益函数。通过比较各种阵列配置方式下的天线方向图副瓣特性及共形天线阵列的方向性增益,综合选取副瓣最小和方向性增益最高的制导武器共形天线阵列的最优配置方式。仿真结果表明,在同等参数配置条件下的圆极化圆锥矩形栅格阵列可以作为制导武器共形天线阵列的最优配置方式。Some kinds of configurations of conformal array are discussed to obtain the optimal special properties of radiation patterns with specific directions in guided weapon systems.The geometrical models of pyramid array and cone array are developed firstly.The radiation pattern and directivity of pyramid array and cone array are built up respectively with different kinds of configurations of the array elements.Then the optimal configuration of conformal array with the lowest sidelobe level and the highest directivity is selected.Simulation results show that the rectangular-grid array on a cone with circular polarization is the optimal configuration of the conformal array in guided weapons under the same parameters.
