Abstract:

Ultrasonic transducers were used to couple the transmission of continuous-wave and pulse-modulated signals across relatively short paths of less than one meter through media of various densities. The experimental model used consisted of two concentric, cylindrical, stainless-steel tanks, one inside the other, with the area between them filled with either water or air. The investigation showed the feasibility of transmitting usable data to and from a unit which was isolated from a data source, i.e., from outside the outer tank to inside the inner tank, and vice versa, without physically penetrating the walls of either tank. An application hypothesis for a Submarine Launched Weapon System is presented as an example of employment of this technique since the weapon vehicle is relatively isolated from the fire-control system and since the elimination of cabling between the launcher and the weapon should enhance system performance.
