Seismic Methods of Locating Military Ground Targets.
Abstract
An approach for locating military ground targets with a triangular array of geophones is presented. An algorithm that relates the characteristics of the signature received at each geophone to the direction of the target is derived. The signatures are then processed by two methods, which have differing degrees of complexity, to estimate target position. The target-location system (including array deployment) was used in field studies to determine directional angles to military targets, including an M113 APC, an M35 2-1/2-ton truck, an M151 jeep, and an M728 (combat engineering vehicle on an M60 tank chassis). A multiple-target test was also analyzed for targets consisting of the M35 and the M151. Estimated and measured angles were then compared. Results of the analysis indicate that the location of targets using strictly seismic energy and acoustically coupled seismic energy is possible within accuracies of 5 deg and ranges exceeding 450 m.
