AbstractAn anti-submarine warfare concept is proposed in which a low-cost and easily-deployable temporary submarine detection zone is created in littoral waters. The concept uses solid-state magnetic field sensors to detect the passage of submarines, and acoustic transmitters to relay the data to a small number of in-water receiver units. The data is then communicated from these units to a manned off-site monitoring platform. The magnetic field sensors are based on the phenomenon of spin-dependent tunneling. This emerging technology demonstrates potential for high sensitivity without the cost, size, or cooling requirements other magnetometer systems.
