The paper describes how the IRHVTA tracker subsystem autonomously selected and tracked points throughout the infrared (IR) sensor's field of view to maintain geometry stabilization relative to the ground. It explains how the acquisition subsystem used this stabilization to interrelate sequential snapshots. This allowed later snapshots to use the acquisition information from earlier ones to reduce the weapon to target uncertainty. The reduced uzxertainty Permitted the searching of smaller areas of the imagery for the later acquisitions. The paper also SCribeS the use of the groundstabilized geometry to transition from acquisition of large landmark objects early in the mission to smaller targets later in the mission with minimized probability of false alarm. The paper concludes with an explanation of the benefits of this design on probability of detection and on operation in the presence of camouflage and decoys. The extension of this design to the attack of invisible aim points is also explained. |
