Passive acoustic methods of small boat detection, tracking and classification
The ability to safeguard domestic shipping and waterside facilities from threats associated with surface and underwater threats (vessels as well as divers) is critical to ensuring security for the maritime domain. Stevens Institute of Technology has been conducting numerous studies and associated field experiments of passive acoustic sensor applications for the detection, characterization, and tracking of surface and underwater threats, which lead to the development of the Stevens Passive Acoustic Detection System (SPADES). The extended diver detection tests were conducted in Newport, Rhode Island and in Den Helder, The Netherlands. Tests involving surface boats were conducted in various locations, including the New York Harbor, Miami, and San Diego. Acoustic tests in Lake Hopatcong, NJ were also conducted in controlled conditions using six distinct boats, including a Panga, a Go Fast boat, a jet ski, and a quiet electrical boat.
