Abstract

Abstract 7. A system for communicating electromagnetic signals through the atmosphere between at least two underwater objects capable of transmitting and receiving electromagnetic signals comprising a transmitter and receiver for said signals carried by each of said objects, first conductive means carried by each said object and disposed within the water for radiating said transmitted signals into the water and producing conductive currents and corresponding fields in the water surrounding said object and capable of receiving incoming signals carried by other conductive currents in the vicinity, second conductive means carried by each said object and releasable by each said object to be disposed at the surface of the water separate from said object and in the vicinity of each of said objects with the ends thereof in contact with the water and capable of receiving the transmitted signals of said conductive currents and to radiate said transmitted signals into the atmosphere for reception by the second conductive means disposed on the surface of the water separate from and in the vicinity of the other object, said second conductive means being capable of detecting said signals radiated through the atmosphere and radiating said signals through said ends into the water and producing conduction currents and corresponding fields in the water surrounding the adjacent object.
