摘要
论述了机动雷达大阵面天线自动展开/折叠的工程原理和所需攻克的关键技术;讨论了利用PLC控制器实现机电式天线自动展开/折叠系统的工程原理;介绍了在国内首次实现的大阵面天线自动展开/撤收技术所具有的技术性能和功能。该天线自动展开/撤收装置已应用于某雷达.通过使用证明性能良好、可靠性高。
This article expatiates the operating theory of an auto-outspread and auto-collapse mechanism which is used in the large-area antenna of a radar with high flexibility. To make this mechanism suitable for such occasion,designer must conquer a pivotal technology. That is to utilize PLC to accomplish the auto-outspread and auto-collapse of the electro-mechanic antenna. The paper introduces the technic capability and function of the large-area antenna's auto-outspread and auto-collapse mechanism firstly used in our country. And it has good performance and high reliability through practical use.
