ABSTRACT TARGET IMAGE PRESENTATION SYSTEM A target presentation system for displaying images of a target on the interior surface of a part-spherical dome provides an observer within the dome with a visual representation of an aerial target flying a flight profile within an airspace surrounding the observer. A projector projects an image carrying beam carrying target images corresponding to those which would be viewed by a ground observer during the flight of the target in the flight profile and directs the image carrying beam to positions on the dome corresponding to those positions of a target traversing the airspace represented by the dome. The projector includes a focus control lens to maintain the image on the dome in focus throughout the visual representation of the predetermined flight profile for a position of the target presentation system within the dome offset from the centre of the dome.
