摘 要:
在图像信号传输或无线通信中，为了保证通信质量，大多采用定向天线。当将定向发射天线和接收天线对准时，才能接收到高质量的信号，但是定向天线对准是一项很困难的工作。针对定向天线对准困难的问题，根据GPS和数字罗盘技术，提出了定向天线自动控制系统的设计方案，进行了精度分析和试验。该系统结构简单，价格便宜，满足高机动武器装备信息传输要求。[著者文摘]

Abstract:
To assure communication quality, directional antenna is usually adopted in image signal transmission or wireless communication. High quality signal is received when directional transmitter antenna aims at receiver antenna. But it is a difficult job. Aimed at the difficulty of directional antenna orientation alignment,according to the technique of GPS and digital compass, the design of directional antenna automatic control system was presented, and analysis of accuracy and test are done. The system has advantages of simple configuration and low price, which can meet the demand of high maneuverable weapon equipment information transmission.[著者文摘]
