This solution does give fair scope visibility, but the operators must work in the dark, and operations must be discontinued whenever light is needed for maintenance of the equipment. This report describes a polychromatic system of lighting radar centers that provides improved scope visibility, permits the use of an illuminated working environment, and makes possible 24-hour radar operations.
