用于对飞行器导航系统中的天线的选择的系统和方法
摘要：
提供了用于对飞行器导航系统中的天线的选择的系统和方法。在一个实施例中，一种用于飞行器的导航接收机系统包括：从固定位置地面发射机接收发射机信号的第一飞行器天线和从所述固定位置地面发射机接收发射机信号的第二飞行器天线，其中，所述第一飞行器天线具有与所述第二飞行器天线的第二增益方向图不同的第一增益方向图；开关，耦合至第一接收机以及所述第一飞行器天线和所述第二飞行器天线；以及开关控制器，耦合至所述开关。所述开关控制器基于对是所述第一增益方向图还是所述第二增益方向图在所述固定位置地面发射机中的第一固定位置地面发射机的方向上提供更高增益的确定，将所述开关操作为将所述第一接收机电耦合至所述第一飞行器天线或所述第二飞行器天线。
摘要（英）：

Systems and methods for the selection of antennas in aircraft navigation systems are provided. In one embodiment, a navigation receiver system for an aircraft comprises: a first aircraft antenna that receives transmitter signals from fixed-location ground transmitters and a second aircraft antenna that receives transmitter signals from the fixed-location ground transmitters, wherein the first aircraft antenna has a first gain pattern that is different from a second gain pattern of the second aircraft antenna; a switch coupled to a first receiver and the first and second aircraft antenna; and a switch controller coupled to the switch. The switch controller operates the switch to electrically couple the first receiver to either the first or second aircraft antenna based on a determination of whether the first gain pattern or the second gain pattern provides higher gain in a direction of a first fixed-location ground transmitter of the fixed-location ground transmitters.
