摘　　要：为解决阵风扰动对遥感卫星数据接收站窄波束天线跟踪性能的影响问题,采用安装天线罩抗风、使用大惯量电机增加天线转动惯量以及优化跟踪策略等方法。通过阵风扰动建模、伺服电机与传动机构建模、控制环路建模以及Matlab仿真,得出减少阵风扰动影响的几种方法,比较几种方法的适用范围、优缺点和可实现性,得出解决遥感卫星数据接收站窄波束天线抗阵风扰动的结论,为以后的工程项目建设提供参考。In order to weaken the influence of gust disturbance on tracking performance of narrow beam antenna of remote sensing satellite data receiving station,the methods of radome anti-gust installation,antenna rotary inertia increase with large in-ertia motor and optimization tracking strategy are adopted.The modeling of the anti-gust disturbance,control loop,servo motor and transmission mechanism,and Matlab simulation are carried out to get several methods for the reduction of gust disturbance.The adaptability,merits and feasibility of the methods are compared to obtain the conclusion that the narrow beam antenna of re-ceiving station of remote sensing satellite data can resist the gust disturbance,which provides a reference for the future engineering project construction.
