    • A radio-based position location system for determining a relative position of a first object with respect to a second object may include a first radio operatively associated with the first object. A first directional antenna having at least a high gain region is mounted to the second object so that the high gain region is directed generally outwardly from the second object and defines a first detection zone. A second directional antenna having at least a high gain region is also mounted to the second object and is oriented so that the high gain region is also directed generally outwardly and defines a second detection zone. A second radio connected to the first and second directional antennas exchanges radio signals with at least the first radio to determine the relative position of the first object with respect to the second object at least in part by determining a time-of-flight of a radio signal. The radio signals are primarily exchanged via the first directional antenna when the first object is in the first detection zone, whereas the radio signals are primarily exchanged via the second directional antenna when the first object is in the second detection zone.
    • 用于确定第一对象相对于第二对象的相对位置的基于无线电的位置定位系统可以包括与第一对象可操作地相关联的第一无线电。 具有至少高增益区域的第一定向天线安装到第二物体,使得高增益区域通常从第二物体向外指向并且限定第一检测区域。 具有至少高增益区域的第二定向天线也被安装到第二物体并被定向成使得高增益区域也大致向外指向并且限定第二检测区域。 连接到第一和第二定向天线的第二无线电与至少第一无线电交换无线电信号,至少部分地通过确定无线电的飞行时间来确定第一对象相对于第二对象的相对位置 信号。 当第一物体处于第一检测区域时,无线电信号主要经由​​第一定向天线交换,而当第一物体处于第二检测区域时,无线电信号主要经由​​第二定向天线进行交换。
