Abstract
Device and a method for locating a mobile object approaching a surface reflecting electromagnetic waves. The location device includes an emission antenna and a reception antenna. The emission antenna has one or more emission positions emitting a detection signal toward the mobile object. The reception antenna has at least one column of one or more reception positions, receiving a signal transmitted by the mobile object. An emission of the detection signal is activated on each emission position. An emission position that produces a detection by the reception antenna, of the signal of maximum energy transmitted by the mobile object, is selected to track the mobile object. One or more signals of maximum energy, received by one or more reception positions, are used to angularly locate the mobile object. The invention can be used to determine the position of an aircraft in the final landing phase for a guidance device.
