A comparative analysis of side-looking sonars for rapid classification of underwater intruders
Pastore, Thomas J.; Kessel, Ronald T. (NURC, 2008/09)One aspect of NURC's 2008 efforts in port protection involves building a prototype system for countering a subsurface threat. Such a capability against underwater intruders in ports requires surveillance of the underwater ... -
At-sea measurements of diver target strengths at 100 Khz: measurement technique and first results
Hollett, Reginald D.; Kessel, Ronald T.; Pinto, Marc A. (NURC, 2006/08)During a recent at-sea trial of a diver detection system, the opportunity was taken of developing a technique for in-situ measurement of diver target strengths. The technique was based on making the diver perform circular ... -
Counter piracy surveillance requirements for early detection, military rescue, or evasion
Kessel, Ronald T.; De Rosa, Francesca (NURC, 2012/06)Best practice for protection against pirates includes coordination with the military forces operating in the area, constant watch against the approach of pirates, and measures to prevent or delay their boarding. The time ... -
Protection in ports: countering underwater intruders
Kessel, Ronald T. (NURC, 2007/10)The advance of new capability depends on many things: the state of the art in technology, the clarity of the mission and requirements, the knowledge of the threat, the means of response, and, for developers, the state of ... -
Security versus defence: dual use from a system requirement perspective
Kessel, Ronald T. (NURC, 2008/09)The developers of defence technologies in both industry and national laboratories carried their culture for military system development into the evolving security mission, even for systems that are to be used by civilian ... -
The dynamics of information fusion: synthetic versus misassociation
Kessel, Ronald T. (NURC, 2006/08)Fusion entails both the association and synthesis of information. If missassociations occur, they obviously undermine the gains won by synthesis, compromising the fusion product. An analytic framework is presented here to ... -
The intrinsic variability of detection range and its implications
Kessel, Ronald T. (NURC, 2009/12)The range of first detection of an approaching target is among the most important parameters defining sensors and defensive surveillance systems. A demonstration of capability typically consists of staged approaches of a ... -
Underwater intruder detection sonar for harbour protection: state of the art review and implications
Kessel, Ronald T.; Hollett, Reginald D. (NURC, 2006/08)Sonar is the sensor of choice for wide-area underwater surveillance because sonar (based on sound waves) typically provides a much larger area of coverage than radar (electromagnetic waves) or video (visible light) can ... -
Unmanned surface vessels for surface and subsurface threats in harbours: background and practical lessons
Pastore, Thomas J.; Kessel, Ronald T. (NURC, 2009/12)The use of Unmanned Surface Vehicles (USVs) in harbour protection missions has been studied through technology surveys and experimentation within the programme of work at NURC. The crucial subsystems and vehicle payloads ... -
Waterside Security 2010 (WSS2010) conference: post conference report
Kessel, Ronald T.; Zakharia, Manell (NURC, 2011/02)The 2nd International Conference on Waterside Security was hosted by NURC, Carrara, Italy, 3-5 November 2010. This report provides summary statistics of the conference, a summary of the workshops, remarks form the WSS2010 ...
