摘要：

截断误差作为近场测试中较大的误差源之一,对它的分析和研究有一定的必要性。为构造出真实的口径场,找出阵中失效单元的位置,以更好地“诊断”天线,文中对截断误差对口径场的影响进行了分析,并用计算机模拟的方法通过构建模型分析了不同的截断角对天线口径场幅度相位的影响。

关键词: 平面近场测量, 截断误差, 口径场

Abstract:

It is necessary to analyze and research truncation error,an error that cannot be ignored in planner near field measurement.To reconstruct antenna aperture distribution and locate defective element and diagnose antenna,this paper analyzes the holograms uncertainty due to truncation.The effect of hologram amplitude and phase on different truncation angle is analyzed by the method of computer simulation.

Key words: planner near field measurement;truncation error;hologram
