Targeting Augmentation with GPS

Jack Moses and B. Lee Kilday

Abstract:	Accurate enemy target location provides the military with critically important data which can inlluence the outcome of a military engagement as has been demonstrated in previous wars and as recently as in Desert Storm. A function which is becoming increasingly important in defense suppression and weapon &livery systems is the ability to provide accurate emitter location of stationary ground based targets so that commanders can take appropriate action to direct weapons against these targets in all types of weather, under any condition, at any time, and with pinpoint accuracy. This can be accomplished from a single moving platform through successive measurements or from multiple platforms which make simultaneous measurements. Techniques in the past have been (1) azimuth/elevation, (2) triangulation, and (3) time difference of arrival (TDGA). This paper discusses these techniques and addresses the augmentation of these techniques with GPS as well as the application of GPS to conventional and synthetic aperture radar. Discussed are (1) GPS/radar using bilateration and (2) GPS/lNS/Synthetic Aperture Radar (SAP). The paper addresses operational advantages/disadvantages and accuracy comparisons of both passive and active systems. Emphasis is placed on an analysis of the improvement in target location accuracy provided by GPS.
