A comparative analysis of side-looking sonars for rapid classification of underwater intruders
(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
(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 ... -
Autonomous underwater vehicles for port protection
(NURC, 2006/07)NATO's present capability to deal with a terrorist threat to our ports is slow, dangerous, and inefficient. Ports are a challenging area within which to conduct MCM operations due to several factors: shipping movements, ... -
Protection in ports: countering underwater intruders
(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 ... -
Review of target strength information for waterside security applications
(NURC, 2008)Estimates of the target strength of objects, such as for example scuba tanks and swimmer delivery vehicles, are parameters of interest in all phases of the design of waterside security systems. Results of numerical target ... -
Underwater intruder detection sonar for harbour protection: state of the art review and implications
(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 ...
