Abstract
A system for aiming a weapon such as an antiaircraft gun at a target which includes in combination an optical sighting mechanism having a movable reticle and a movable target mark associated with the movable reticle, digital to rotational motion transducers coupled to the movable reticle and the movable target mark and a digital computer adapted to receive inputs indicative of the azimuth and elevation of the target as well as its estimated velocity and ballistic characteristics of the ammunition used. The computer is programmed to compute the flight path of the target and a lead angle based upon certain trigonometric relationships and provides a digital output to the digital-to-rotational motion transducers to position the reticle and target mark in the optical sighting mechanism.
