Abstract : A 360 degree closed circuit television system is disclosed which includes six background scene cameras, each camera of which scans a sixty degree segment of a background scene appearing on a 360 degree reflective display screen, and each camera of which provides a background information signal in response to scanning of the background scene; and six target cameras, each target camera of which scans a target, and each camera of which provides a target information signal in response to scanning of the target. The background scene and target information signals are then supplied to an electronic gating circuit which synthesizes the background scene and target information signals so as to produce six background scene target information signals. Each background scene-target information signals activates one of six projectors with each projector, in turn, broadcasting a sixty degree segment of the background scene upon one screen element of a hexagonal shaped transparent display screen. In addition, each projector broadcast on the transparent display screen the target for a predetermined time period such that an observer will observe the target moving around the transparent display screen is controlled by a digital computer in accordance with a target movement program.
