Abstract : The purpose of this work was to assess experimentally the feasibility of locating ground vehicles by time correlating vehicle sounds relayed by two or more separated 'sensors'. Acoustics were selected because useful ranges of one to two kilometers are possible, as far as ground sources are concerned, and because acoustic signatures, although very complex and difficult to deal with, contain a wealth of information which if properly treated by using correlation techniques the following could be achieved: (a) determination of location; (b) ability to track; and (c) ability to discriminate (count and identify).
