High performance single reflector compact range
-
摘要: 介绍了一个单反射面紧缩场,其反射面实体由多块面板拼装而成.单块面板成形基于"点阵钉模、真空负压、金属蜂窝"精密成形工艺,平均精度达到25μm(rms),拼装后总体形面精度达到40μm(rms).通过优化电气布局、边缘设计和馈源设计,该紧缩场具有优良电性能.给出了该紧缩场在39GHz时电性能实测曲线.Abstract: A single reflector compact range (CR) was presented. The reflector itself was made up of individual accurately fabricated panels. The precise forming of each panel was based on "nails die, vacuum and honeycomb sandwich" method. Average surface accuracy of these panels was 25 micron rms and surface accuracy of the reflector as a whole was 40 micron rms. Through optimizing electrical geometrical layout, reflector edge design and feed design, high performance was acquired. Practical testing results at 39GHz were presented.
