Fish Ragu (Fish, Radio-Receiving and Generally Useful).

Abstract

The concept of using of 50kg self-propelled body as a receiver for VLF signals is presented. This 'fish' would operate a few meters below the surface and communicate to a submarine via high frequency acoustics. Zinc oxide batteries provide sufficient power for all of the 'fish's' operations including a 24 hour endurance at a 4 knot speed. The 'fish' could also be used as a sonar receiver, a sensor of submarine radiated noise and as a VHF or UHF receiver. (Author)
