A human locator system and method conducts long-range locating with
components or steps that are not readily visible on the person of the
lost human, and that is fully independent of external communications and
power systems. The human subject is provided with a beacon that may be
concealed on or in the body, which is activated to produce a signal which
may be sensed by a sensor or receiver deployed to scan a field of search
in which the human subject may be located. The beacon indicates a signal
origination point that is indicative of the location of the human subject
by differentiating the human subject in a pre-arranged manner from the
background region in which the human subject is located.
