DEVICE AND METHOD FOR LOCATING A MOBILE APPROACHING A SURFACE REFLECTING ELECTROMAGNETIC WAVES

摘要

The invention relates to a device and a method for locating a mobile approaching a surface reflecting electromagnetic waves. The location device (40) includes a transmission antenna (42) and a reception antenna (41). The transmission antenna (42) has one or more transmission positions (47) for emitting a detection signal towards the mobile. The reception antenna (41) includes at least one column (43, 44) of one or more reception positions (46) for receiving a signal retransmitted by the mobile. A transmission of the detection signal is activated on each transmission position (47). A transmission position (47), resulting in the detection by the reception antenna (41) of a maximal-energy signal retransmitted by the mobile, is selected for tracking the mobile. One or more maximal-energy transmission signals received by one or more reception positions (46) are used for the angular location of the mobile. The invention can for example be used for determining the position of an aircraft at the final landing phase in a guiding device.
