提出了一种基于定向天线和信号覆盖差异的定向方法，根据信号覆盖范围的差异来进行定向定位。具体定向原理为: 信号发射终端向不同方向发射不同信号，这些信号覆盖范围会有不同程度的重叠，因此接收终端能够接收到一到多个不同信号，然后根据发射终端信号覆盖图，就可以分析出接收终端相对发射终端的方向。该方案不需卫星定位信号和移动数据网络服务，不需要预先铺设定位节点就可实现定向定位。

An orientation method based on directional antennas is proposed according to the difference of signal coverage area. The transmitter transmits different signals to different directions, and the coverage areas of different signals would be overlapped to some extent, therefore the receiving terminal can receive one or more different signals. By analyzing the signals received, the receiving terminal’s direction relative to the transmitting terminal can be determined according to the transmitter signal overlay. The proposed orientation method can determine the direction without satellite positioning signals, mobile data network services or paving locating nodes in advance.
