Investigation of ELF Signals Associated with Mine Warfare: A University of Idaho and Acoustic Research Detachment Collaboration
Abstract
The questions that are being asked in this investigation are: (1) once an ELF signal is generated, how far does it propagate and still be detectable and (2) how can such signals be modeled, excited and measured? To this end, the scenario considered is one in which an ELF source of the electric or magnetic kind is located in or above water, such as a lake or ocean. This source stimulates an ELF signal that is free to propagate in the water and air, and is reflected by various material interfaces, say between the water and air, or between the water and the floor. For purposes of experimental demonstration, the investigation focuses on the scenario of ELF sources and signals in the context of Lake Pend Oreille, where the Acoustic Research Detachment (ARD, Bayview, Idaho) is located and entrusted with the necessary assets to perform validation measurements.
