Investigation of various display techniques for remote control of aircraft has resulted in the development of an experimental hemispherical rear projection TV system. The original concept, being developed by NWC, was to use a wide-angle TV camera in a target type aircraft to simulate a pilot's visual frame of reference for display to a ground controller (Fig. I).
