Feasibility Study for an Underwater Detection System
Abstract
The report describes the design and test of a feasibility model of an electromagnetic swimmer detector. Operating at a frequency of 400 KH sub z, this system responded to conductivity changes caused by the presence of a swimmer near three 14 feet dipole antennas. The antenna array was deployed in an area of 140 square feet underwater. Swimmers were detected at ranges up to seven feet above the antenna array. Underwater path loss and antenna impedance measurements are reported.
