摘　　要：天线测量多数在微波暗室和外场测试进行,但是因暗室的造价高昂而少有配置,而外场测试场测量结果易受多路干扰影响。因此,基于雷达栅技术,文章提出一种外场天线测试的改进方案。分析并仿真了雷达栅布置的位置、高度、宽度之间的相互关系以及应满足的约束条件,最后进行了实物测量,仿真和外场实测结果接近,证实了所提方案的有效性和实用性。该方案具有结构简单、成本低等特点,同时也较好地满足教学、科研等基本需求。Antenna measurements are mostly performed in microwave anechoic chambers and outfield testing,but the anechoic chambers are expensive and rarely configured, and the measurement results in the outer and near-earth test fields are easily affected by multipath interference.Therefore, based on the traditional field test, this paper introducesthe radar fence, and analyzes and simulates the relationship between the position, height and width of the radar fence layout and the constraints that should be satisfied,finally, the engineering implementation is carried out. The simulation results are close to the outfield testing measurement results, which proves the effectiveness and practicality of the proposed scheme. The scheme has the characteristics of low cost and simple structure, and also better meets the basic needs of teaching and scientific research.
