Abstract
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).
