本文研究了工作波长为8毫米和13毫米的机载微波辐射计用的天线罩。其天线为前馈式旋转抛物面,口径为400毫米,飞机的最大航速小于每秒100米。文中不但给出电气设计公式和图表,而且附有产品照片和实验数据(功率传输系数,驻波变化和天线有和无罩时的方向图),同时对工艺流程作了简要的介绍,为毫米波天线罩的制作提供了宝贵的经验。由于当时买不到DAP树脂,本产品用199号树脂来代替,仍能满足使用方功率传输
In this paper, radomes for airborne microwave radiometers with operating wavelengths of 8 mm and 13 mm are studied. The antenna is a feed-forward rotating parabola with a caliber of 400 mm and a maximum speed of less than 100 meters per second. In this paper, not only the electrical design formulas and diagrams, but also the product photos and experimental data (power transmission coefficient, standing wave variation and antenna with and without the cover of the pattern), and a brief description of the process, the millimeter The production of wave radome provides valuable experience. Because at that time can not buy DAP resin, the product is replaced by 199 resin, still can meet the user side power transmission
