A mobile navigation system includes a directive beamforming antenna carried by the vehicle, emitting first and second sensing beams in first and second directions at first and second time points, respectively; an electromagnetic wave reflector installed in the target zone, receiving the first and second sensing beams, and transmitting first and second retro waves back; and a processor electrically coupled to the directive beamforming antenna, receiving the first and second retro waves, and determining a direction where the vehicle will be guided to move according to information of the first and second retro waves. A coverage area of the first sensing beam and a coverage area of the second sensing beam partially overlaps with each other, and the direction where the vehicle will be guided to move lies between the first direction and the second direction.
