炮瞄雷达天线点头搜索机构的设计
摘要
如果说雷达是其他设备的眼睛，那么天线就是雷达的眼睛。随着科技的不断发展，雷达的应用也愈加广泛，无论是从扫描范围还是定位精度对雷达的要求也越来越高。如何不断提高雷达的综合性能已经成了亟待解决的问题。
针对以上问题，在此主要是通过设计一种机械机构使得雷达天线在周向扫描的同时以一定的频率做点头运动，从而增大雷达波的覆盖范围，提高雷达发现目标的概率。
首先通过对国内外雷达天线搜索机构进行综合了解，然后确定所要研究的内容。明确研究方向后通过综合分析确定雷达点头所需的机构，进而进行各零部件的设计，然后将各部件、机构进行组装，完成主体设计内容。最后是对设计内容进行校核，验证设计内容是否符合要求。

Fire Control nod search agencies in the radar antenna design
Abstract
Antenna is the eyes of the radar, just as radar is other equipments’ eyes. With the development of technology, the application of radar is becoming ever-widening. It requires the radar to be high performance whether from scanning range or positioning accuracy. How to improve the comprehensive performance of radar has become a problem to be solved.
According to these issues , in this article we design a mechanism which makes radar turn weeks to scan accompany with doing nod movement at a certain frequency. This kind of radar may enlarge the radar coverage, and increase the probability of founding the goal.
A first, we should make a synthesis understanding on the domestic and international radar, to confirm the content of the study. After clearing the direction, we do comprehensive analysis to determine the radar nod institutions needed, which state the design of the parts. And then, components and mechanisms are assembled, so is the main body design content completed. Finally, the design content is checked to find out if it is comply with the requirements.
