MID RANGE UV COMMUNICATIONS

Abstract

Mid-range communications are improved with a transmitter having an elongate omni-directionally radiating tube of UV energy that are focussed by a compound parabolic reflector to within a designated azimuth and/or elevation. The configuration of the reflector gives a broad beam directivity over a receiver target area to the exclusion of other bearings and elevations such that selected receiving stations can be designated between moving or unstable communication platforms, such as aircraft or ships. Because scattering occurs at angles larger than the direct beam, the requirement for accurate tracking mechanisms is further relaxed. Furthermore, these extra scattered photons increase the link distance. The need for very small divergence transmitters, like lasers, is eliminated permitting inexpensive, efficient UV lamps to be used with compound reflectors as transmitter sources.
