ABSTRACT:
A system and method for providing a relative velocity sighting reference in an airborne gunsight system. A head-up display (HUD) frames the target in the pilot's line of sight and a computer-driven cathode ray tube (CRT) display projects an array of sighting indices or dots on the HUD. The computer receives air data and target tracking inputs and controls the CRT display so that the sighting array automatically overlays and follows the target and so that the indices thereof move in a direction and at a velocity to describe the motion of the line of sight of the target required for the target to intercept a bullet fired from the aircraft gun. The pilot maneuvers the aircraft to null the relative motion between the target and the sighting indices, whereby the gun is in position to fire.
