摘要
天线是无线通信领域必不可少的一个器件,无论在工程领域还是实验室的研究中,都需要对天线相关参数进行测量与处理以分析其性能,因此设计了一种基于液晶显示的天线测量系统。该系统以STM32为核心,由信号采集与数据处理电路、云台驱动电路、按键和液晶显示电路以及U盘存储电路组成。实现了云台的自动控制、方向图的自动绘制、天线测试参数的自动计算以及数据的自动存储的功能。该系统性能稳定,操作简单且便于携带。
Antenna is an important device in the field of radio communication.It is necessary to measure and analyze the antenna parameters for both engineering field and laboratory studies.Therefore,an antenna measurement system is designed based on Liquid crystal display.The system takes STM32as the core and consists of signal extraction and data processing circuit,cradle head driving circuit,key press and LCD display circuit,and USB storage circuit.The system can realize the functions of automatic control of the antenna turntable,automatic drawing of antenna pattern,automatic calculation of antenna test parameters and automatic storage of data.The system has stable performance,simple operation and is easy to carry.
