Abstract

Abstract A sight system for providing closed-loop differential tracking control over gun aiming, utilizing visual and non-visual optical radiation to assist the gunner in acquiring and destroying targets as well as providing information to the gun control computer for automatic acquisition and firing. The sight is used in conjunction with a cooperative ammunition round which emits pulsed flashes at a timed interval after firing and upon impact. Portions of these signals are in the non-visible spectrum, and an invisible-to-visible converter is utilized to signal the relative location of the flashes to the gunner. A similar conversion is utilized to provide information on laser designator illumination and other non-visible radiation emanating from the target.
