摘　　要：文中采用软件无线电和智能天线技术构建工作在中波和超短波波段的自动无线电罗盘。中波信号用固定环形天线和垂直天线接收,通过数据据解算获得方位信息。超短波信号用圆形天线阵接收,采用MUSIC算法检测方位信息。采用这种方案设计的罗盘硬件结构简单,具有通用性,而且定向速度和定向精度比一般的罗盘有显著提高。Constructing a automatic radio compass with soflradio and smart antennas technologies working in medium wave and ultrashort wave. With fixed round antenna and vertical antenna accepting the medium wave singal, by accounting data to get the direction information. With circular antennas accepting the Ultrashort wave signal, by MUSIC arithmetic to measure direction information. This type of compass have simple hardware structure, compatibility and great improve in speed and precision of finding direction.
