INVESTIGATIONS OF VERY LOW FREQUENCY DETECTION TECHNIQUES IN A SEA MEDIUM.

Abstract

This document presents the results of theoretical and experimental researches into the detection problem of submerged metallic objects by means of ULF electromagnetic, E/M, energy. Analyses of a conductive medium's E/M transmission characteristics, and propagation mechanism are developed. Elements of system design considerations including an examination of reflector qualities and submerged coaxial antenna properties are presented. Field experiments demonstrating a near-surface and near-bottom detection techniques are described and their results discussed. Finally a plan of approach is presented showing a course for the contained study of electromagnetic methods in the detection of submerged metallic objects. (Author)
