Abstract
Aiming system for firearms of the type for use when a target is obscured for example by darkness or camouflage include a sighting arrangement which comprises an imaging device of sufficiently small size to be carried on the firearm. These imaging devices consequently have small apertures and low resolution and are therefore of limited value. The aiming system disclosed herein has an imaging device remote from the firearm which forms a background image of a given field-of-view, the image being displayed on a screen. The system includes a second imaging device carried by the firearm and having a smaller field-of-view corresponding to the line-of-sight of the firearm. The images produced by both imaging devices are correlated by a correlator and a sight-mark is generated in the background image to indicate the line-of-sight of the firearm when correlation is obtained.
