Method and apparatus for location determination

摘要

A location determination device ( 104 ) is worn on a user's head to facilitate searching and tracking for another individual carrying a portable radio ( 102 ) as well as locating exit routes. At least two antennas ( 108 ), a monopulse receiver ( 110 ) and a display are integrated into the location determination device ( 104 ). Location determination device ( 104 ) scans for an incoming signal ( 106 ) from the portable device ( 102 ) and coverts the signal into angular location data. The location data and egress information are displayed to the peripheral vision of the user of the location determination device ( 104 ).
