SQUID ELF Receiving Antenna for Submarine Applications.
Abstract
An ELF receiver using a triaxial array of superconducting quantum interference devices (SQUIDs) can provide an omnidirectional receiving capability unobtainable with conventional ELF antennas. The ELF SQUID receiver development program has undertaken (a) achievement of a prototype SQUID device with sufficient sensitivity, dynamic range, and linearity; (b) determination of the motion spectrum for a candidate receiver platform; (c) design of a motion processing technique to remove residual motion noise; and (d) provision of a suitable cryogenic environment. Two prototype SQUID antennas, one using point-contact sensors and the other using thin-film sensors, were procured and tested.
