<p>A fire control system for a gun comprises a means 10 for determining the position of a target, computer 14 which receives signals representative of the target position from the means 10 and computes fire control signals according to a known programme, the fire control signals being transmitted to a gun drive mechanism 16. The means 10 includes an optical sighting device 11 containing a visual display 30 on which two images are presented in superimposition. One of the images is of the field of view containing the target while the other image is a pattern of predetermined character which is controllably movable over the visual display by adjustment devices 32A, 32B under control of the operator. The means 10 further includes a ranging device 12 and a manually controllable element 21 for altering the field of view. The arrangement is such that a target is located within the field of view as a result of adjustment of the element 21 for altering the field of view. Subsequent movement of the target is then determined by operator operation of the manually adjustable means 32A, 32B so that the direction and rate of movement of the pattern image on the visual display is synchronised in direction and speed with that of the target, the status of the manually adjustable means 32A, 32B being fed to the computer 14.</p> |
