Abstract
An improved target sighting device operable to converge on targets whose initial velocity has caused its image to move a significant fraction within the field of view during the period between detections utilizing less electrical circuitry and only one focal plane detector array. A detector array and associated signal processing system for incorporation within an electro-optical tracking system, the detector array comprising both fine track and coarse track detector elements wherein fine track and coarse track detector elements are further interconnected to hybrid fine track and coarse track signal processing algorithms. The resultant signals from the fine track and coarse track detections on the hybrid array will result in commands to gimbals about reflecting means or about a receiver telescope allowing the reflective means or receiver telescope means to be repositioned towards the target with greater accuracy.
