X-Y 型天线座构型设计

摘要

文中研究了天线座的工作原理及结构特征，由于A-E型天线座存在天顶的跟踪盲区，致使其无法完成过顶目标的跟踪任务。 X-Y型天线座将天线的跟踪盲区转移到X轴的两端，即地平线上，因此可满足天线跟踪过顶目标的任务要求。同时，结合实际工程应用，提出了几种不同构型的X-Y座架型式，以及各自的技术指标及适用范围。文章面向实际任务进行机构设计，研究内容对于X-Y型天线座架设计具有重要的指导意义。%This article studies the working theory and structure character of antenna pedestal .Because of the zenith tracking blind zone , A-E style antenna pedestal could not satisfy the tracking demand .X-Y style anten-na pedestal moves the blind zone to the two sides of X axis ( the horizon) , therefore satisfying the tracking de-mand.According to the project applications , several different configurations of X-Y style pedestals are pro-posed, including their specifications and applicability .The design in this article is project-oriented, therefore its results have important guidance meaning for the design of X-Y style pedestals .
