多目标规划的天线相位中心测量方法研究

提出了一种基于多目标规划的天线相位中心测量方法.通过截取主波束一定范围内的多个切面，将该区域的相位中心求解转化为多目标规划的最优值问题.利用线性加权和法将不同切面的多目标规划转化为单目标最优值问题，最后使用差分进化算法求解天线在该区域的相位中心.文中对一个圆极化天线进行测量和计算分析，证实了该方法的有效性.试验结果显示该方法测量的天线相位中心稳定度小于1 mm.

Antenna phase center measurement method based on multi-objective programming

An antenna phase center measurement method based on multi-objective programming is proposed. By obtaining multiple planes in the main lobe, the calculation of antenna phase center is changed into the optimal value of multi-objective programming. Then linear weighted sum method is used to solve the problem. It can change the multi-objective programming into single-objective optimization. Finally, the antenna phase center is solved by using differential evolution algorithm. In order to validate the proposed method, a circularly polarized antenna is calculated and measured. The measured results show that the obtained antenna phase center stability using the proposed method is less than 1 mm.
