ABSTRACT:
A gun aiming system having target ranging means, wherein the operator observes the position of backscattered radiation from a bullet or bullets at the target range relative to a simultaneous visually observed target position. A diverged laser beam is reflected back from a special reflector in the rear of the bullet and received in an optical system which produces an image-like indication in an operator's combining glass. A range gating technique images only the bullets at the same range as the target. The resulting real-time display of the target and the bullet in the target plane simultaneously permits the operator to place the direction of fire so that the two images coincide, thus producing a hit.
