ABSTRACT:
Various items of information are transmitted to a body moving above the surface by a pulsed fan-shaped beam of radiant energy having a flatwise angular sweep. Each such item can comprise two or more kinds of data, e.g., beam angle data and beam identification data. To each different item to be transmitted is assigned a unique whole number. Every interval between successive beam pulses has a duration equal to a non-characterizing time period of invariant duration plus a stepwise variable characterizing time period measurable in a whole number of short, uniform time units. The number of such time units in the characterizing time period of an interval corresponds to the number assigned to an item of information to be transmitted during that interval. At the body, clock pulses are generated at a steady rate such that a whole number thereof are issued per time unit, and are counted during the characterizing period of each interval, for decoding the then-transmitted item of information.
