The research being conducted in the Center for Secure and Resilient Maritime Commerce (CSR), a DHS National Center of Excellence for Port Security examines some basic science issues and emerging technologies to improve the security of ports and inland waterways, as well as coastal and offshore operations. This research follows a layered approach utilizing(More)
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(More)
A test bed was developed for Plum Island, NY experimental multi-sensor security surveillance. The system includes broadband radars, cameras, an Automatic Identification System receiver, geophones and underwater passive acoustic sensors. The sensors were grouped into nodes connected to a Command and Control Center via a Wi-Fi network. Some sensors are COTS,(More)
The international rules for the protection of harbors against threats and intruders typically apply to threats emanating from the land side. Protection against actions and threats from the water side is much less regulated, apart from some individual cases. Potential threats from the water side may consist of intruders including divers with and without(More)
Low Flying Aircraft (LFA) may be used to smuggle illicit drugs or illegal immigrants across borders. Sound radiated by LFA was used for their detection, tracking and classification by the developed Acousto Seismic Air Detection (ASAD) system. ASAD consists of several nodes, where each node has five microphone clusters and three geophones. Single ASAD node(More)
Stevens Institute of Technology in cooperation with the DHS Science and Technology Directorate and the U.S. Customs and Border Protection has been investigating engineering solutions to augment the current inspection process at ports of entry in an effort to minimize the threat posed by invasive species. This paper presents the initial results of acoustic(More)
The effect of modulation of high frequency ship noise by propeller rotation frequencies is well known. This modulation is observed with the Detection of Envelope Modulation on Noise (DEMON) algorithm. Analysis of the DEMON spectrum allows the revolutions per minute and number of blades of the propeller to be determined. This work shows that the high(More)
This paper discusses technology solutions that may be used to mitigate potential threats and security risks arising from small vessels operating in a busy urban maritime domain such as the New York / New Jersey maritime domain. The solutions focus on persistent surveillance by detecting, tracking, and classifying small vessels, and address the risk posed by(More)
Stevens Institute of Technology has been investigating engineering solutions to augment the current inspection process at ports of entry in an effort to minimize the threat posed by invasive species. Stevens has built several sensitive acoustic systems for detection of tiny acoustic/vibrational signals produced by moving insects and tested them in two US(More)
Passive acoustic methods can detect, track and classify surface and underwater vessels. We consider the application of these systems for DHS interests with attention to small boats. We present a review of various methods of detection and tracking for low-cost low-power systems with a few hydrophones. The analysis of acoustic signatures of boats to determine(More)
