摘要/Abstract

摘要： 基于紧缩场(Compact Antenna Test Range, CATR)工作静区移动的电磁目标模拟器,采用多馈源紧缩场射频信号馈电实现辐射反射面紧缩场得到模拟远场的静区移动,可用在多目标移动环境下的导引头的模拟方面。研究仅通过改变1×4毫米波喇叭馈源阵的相位,控制主波束的指向,来实现CATR工作静区的移动。目标模拟系统的毫米波静区的相位一致性决定目标模拟精度,详细分析了馈源阵水平方向波束指向分别为±5°、±10°时,椭圆形工作静区在沿±y轴方向移动时幅度波动和相位一致性,沿x轴的静区利用率达到了28.1%以上。

Abstract: Electromagnetic target simulator based on CATR of the quiet zone movement,which adopt the multi-feed source CATR RF signal feeding by reflecting to get the quiet zone movement of simulated far field. It can be used in simulation of seekers in a multi-target mobile environment. The phase of the feeds of the 1×4 horn array is changed to realize the movement of the quiet zone in the CATR. The phase consistency of the millimeter wave quiet zone of the target simulation system determines the target simulation accuracy. The amplitude and phase characteristics of the array feeding with different beam directions are analyzed in detail. When the main beam points at ±5° and ±10°, the amplitude and phase distribution of the elliptical quite zone moves along the ±y-axis direction respectively. The utilization rate of the quiet zone along the x-axis reaches more than 28.1%.
