摘要
本文使用有源单元方向图法来实现阵列天线的方向图综合。首先通过电磁仿真软件提取阵列天线有源单元方向图,然后在自行编制的基于遗传算法的程序上综合计算出符合目标方向图(余割函数形状方向图)的阵列幅度相位分布。最后在C波段双极化振子天线阵列中输入本算法综合计算出的幅度相位,验证本算法的吻合性。
This paper uses the active element pattern method to realize the pattern synthesis of the array antenna.Firstly,the directional pattern of the array antenna active unit is extracted through the electromagnetic simulation software,and then the array amplitude and phase distribution in accordance with the target directional pattern(cosecant function shape directional pattern)is comprehensively calculated on the self-made genetic algorithm-based program.Finally,input the amplitude and phase calculated by the algorithm into the C-band dual-polarized dipole antenna array to verify the consistency of the algorithm.
