某相控阵天线阵面静态仿真分析

内容简介：文中针对某相控阵扫描天线阵面变形对天线电性能影响的评判问题,提出了一种最佳吻合平面的算法,用以区分相控阵天线阵面的刚体位移和结构变形;建立了该天线的有限元模型,对天线进行重力和温度载荷分析,利用最佳吻合平面算法对仿真数据进行后处理,分别得到天线阵面的静态平面度误差和方位指向误差。

Abstract：Aiming at the electrical performance judgment problem of a phased array antenna,this paper presents an algorithm of best consistency plane to distinguish rigid body displacement and structural deformation of the phased array.The finite element model of the antenna is established to analyze the gravity and temperature load.Simulation data are post-processed by the best consistency plane algorithm,static flatness error and azimuth pointing error of the array are obtained.
