摘要

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。

Abstract

The application of the new nonlinear optimization algorithm to antenna array design is demonstrated by low sidelobe pattern optimization synthesis of axial dipole arrays on cylindrical surfaces. By use of realized gain patterns（RGP） of array elements

we formulate array synthesis as a nonlinearly constrained optimization problem

and use a new direct method to solve this problem. The technique allows one to find a set of array coefficients that yield a pattern meeting a specified sidelobe level with the maximum directivity

if such a set of array coefficients exists. If the specifications cannot be met

the technique will result in a set of array coefficients that yield a pattern meeting the best attainable sidelobe level and having the directivity as high as possible. Also

some numerical results for low sidelobe pattern synthesis are given.
