摘　　要：为了进一步扩展微小型无人机中继通信的覆盖范围,提高通信带宽和通信质量,设计研制了基于信号接收强度(RSSI)盲估计跟踪的天线自动跟踪平台,通过实时获取通信接收机的RSSI实现地面定向天线对中继无人机的动态跟踪。采用卡尔曼滤波算法对提取的RSSI信号进行优化处理;利用矩形扫描方式提高初始捕获速度;利用单天线步进式"十字"跟踪方法完成天线动态跟踪。设计了自动跟踪平台的软硬件并进行了测试,结果表明:设计的跟踪平台具有较好的跟踪速度与跟踪精度,能满足无人机对定向天线自跟踪的需要。In order to further expand micro unmanned aerial vehicle relay communication coverage, improve the communication bandwidth and quality, a blind estimation tracking antenna automatic tracking system based on RSSI is designed and developed to dynamically track MUAV implemented by acquiring real-time communication receiver RSSI. Optimizing the RSSI signal by using the Kalman filtering algorithm; improving the initial capture speed by using rectangular scanning method; using single antenna step into ＂cross＂ tracking method to complete tracking antenna. The hardware and software of the automatic tracking system are designed and tested. The results show that the tracking system has a good tracking speed and tracking precision.
