ABSTRACT:
A target image presentation system for displaying images of a target on the interior surface of a part-spherical dome to provide for an observer within the dome a visual representation of an aerial target flying a predetermined flight profile within an airspace surrounding the observer comprises a projector for projecting an image carrying beam carrying images of the target for projection on to the dome and an image beam deflection assembly for so deflecting the image carrying beam as to direct the target images carried thereby to positions on the dome corresponding to the positions of the aerial target flying the predetermined flight profile in the airspace represented by the dome. The image beam deflection assembly is of such a construction that when deflecting the beam it introduces a rotation of the image about the beam axis and the projector is arranged to generate target images which are oriented to compensate for image rotation by the image beam deflection assembly so that the images when projected on to the dome by the image deflection assembly 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.
