本文利用新的非线性最优化方法讨论圆柱面上的轴向偶极子阵的低副瓣方向图优化综合问题。利用阵列的单元可实现增益方向图。我们把阵列综合问题表述为一个约束非线性规划问题,采用新直接法求解该问题即可得出一组使阵列的总方向图满足副瓣指标要求,同时具有尽可能高的方向性系数的激励系数。如果阵列的总方向图不能达到副瓣指标,则可得出一组使阵列方向图在可达到的副瓣方向图综合设计的模拟计算结果。
In this paper, we use the new nonlinear optimization method to discuss the optimization of the low sidelobe pattern of the axial dipole array on a cylindrical surface. The gain pattern can be achieved using the array’s cells. We present the array synthesis problem as a constrained nonlinear programming problem. Using the new direct method to solve the problem, we arrive at a set of rules that make the total pattern of the array satisfy the requirements of the sidelobe specification, with the highest possible directivity coefficient coefficient. If the total pattern of the array fails to meet the sidelobe index, then a set of simulation results are obtained that allow the array pattern to be synthesized in the reachable sidelobe pattern.
