ABSTRACT:
An over the horizon communications system includes a transmitter for generating a signal to be communicated, an acoustic source located on the earth in a direction from the transmitter that the communication is to take place which is capable of providing periodic variations in the density of the atmosphere, and means for directing the transmitter at the variations to cause the signal to be redirected over the horizon to a point of reception. The point of reception may be a radar target and the signal may be returned, or the point of reception could be a communication receiver.
