引言用来支撑夭线,馈电系统,承载发射机和接收机的某些部件,使天线波束指向目标,或者按照所需的规律运动的装置(支承、定位和转动装置)叫做天线座架,简称天线座。天线座架不仅是雷达机械结构的重要组成部分。也是天线控制系统的一个重要组成部分。天线座架对雷达整机精度、可靠性、成本、加工周期等影响很大。近年来,随着无线电科学的飞速发展,天线和天线座架发展很快,日见增多。根据不同的使用要求,其天线座架要求不一,型式多样,变化较多。就卫星通信地面站天线来说,根据天线口径大小,有小至
INTRODUCTION Devices (support, positioning and rotation devices) used to support the antenna, feed system, certain components that carry the transmitter and receiver, the antenna beam to the target, or the desired pattern of motion, are referred to as antenna mountings, Referred to the antenna base. Antenna mount is not only an important part of the radar mechanical structure. It is also an important part of the antenna control system. Antenna mount on the radar accuracy, reliability, cost, processing cycle and other great influence. In recent years, with the rapid development of radio science, the antenna and antenna mount develop rapidly and increase day by day. According to different requirements, the antenna mount requires different types and variations. For satellite communications ground station antenna, according to the size of the antenna aperture, as small as
