摘要： 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.

摘要： A system for displaying target images 17 on the interior surface of a part-spherical dome 11 to provide for an observer eg. a trainee gunner, within the dome a visual representation of an aerial target flying a predetermined flight profile within an airspace surrounding the observer comprises a projector 13 and an image beam deflection assembly (22, Fig 2) for so deflecting the image-carrying beam as to direct the target images carried thereby to positions on the dome 11 corresponding to the positions of the aerial target in the airspace represented by the dome. The deflection assembly (22) is of such a construction as to introduces a rotation of the image 17 about the beam axis and the projector 13 is arranged to generate target images which are oriented to compensate for image rotation by the deflection assembly so that when projected on to the dome they have line-of-sight orientations corresponding to those which would be viewed by an observer during the flight of the target in the predetermined flight profile.
