Document Type and Number:
Japanese Patent JP6644740
Kind Code:
B2
Abstract:
A mobile navigation system includes: a radar antenna (100) carried by the vehicle (105), and emitting first and second sensing beams at first and second time points, respectively; first and second retro-directive antenna (120)s or beam-reflecting objects disposed at first and second positions, respectively, and being a specific distance from each other; and a processing device (130) electrically coupled to the radar antenna (100). The first and second retro-directive antenna (120)s or beam-reflecting objects respectively return first and second retro waves corresponding to a direction of the first sensing beam, and respectively return third and fourth retro waves corresponding to a direction of the second sensing beam. The processing device (130) receives the first, second, third and fourth retro waves, and determines a moving direction of the vehicle (105) according to the first, second, third and fourth retro waves and the specific distance.
