摘　　要：本文针对解决气象火箭探测中定向天线跟踪问题,设计基于MEMS测姿器件的天线控制器。主控计算机根据预先设定的火箭运行轨迹,通过MEMS测姿器件实时测定天线方位和俯仰的二维位置,与预先轨道的数据比对,得到二维位置差,将位置差转换成控制命令通过异步串口发送给单片机,单片机通过电磁继电器驱动云台电机的运转,动态实时补偿天线指向预定的方位和俯仰,从而实现对目标的精确跟踪。This article addressing the meteorological rocket detecting directional antenna tracking, the design is based on attitude measurement devices MEMS antenna controller. Host computer is running a rocket based on pre-set trajectory, through the MEMS device is real-time determination of attitude measurement antenna azimuth and elevation of the two-dimensional position data with the pre-track comparison of the two-dimensional position to be poor, it will be converted to control commands through the asynchronous serial port to send to the MCU, MCU through the electromagnetic relay driver PTZ motor functioning, dynamic real-time compensation predetermined antenna pointing azimuth and pitch, in order to achieve accurate tracking of targets.
