Sensing Technologies for Maritime Security
Tuesday 9th November 2010, 1400hrs–1530hrs
Chaired by David Wyllie Enabling Technologies Research & Developments to Cope with Asymmetric Threats Dr Carlo Falessi, Selex Sistemi Integrati, Italy Continuous Enabling Technologies Researches and Developments to cope with asymmetric threats and to compete in the world open market are mandatory. Selex Sistemi Integrati is investing on R&D more than the 17 % of the annual revenues and basic technologies development are in our core business. We are developing Gallium Nitride (GaN) foundry and related solid state technologies, state of the art microelectronics, photonics and nano-technologies, middleware for platform and network centric applications, large scale and complex systems software tools and methods. This presentation will focus in detail on R&D for:
GaN, Microelectronics and Photonics transmit/receive modules technologies for Active Array Multi Functional-Band-Domain applications;
TeraHz amplifiers based on Single Wall Carbon NanoTubes for Security applications. Finally we will outline researches on Muon Tomography Scintillanting Fibers for Containers High-Z detection and the adoption of Phased Array Blumlein Antennas for Direct Energy Stopper Systems in Anti-Piracy applications. Multistatism Commander Gwendal Le Moigne, French Navy, France The technological improvements in the domain of acoustics, sonars and data treatments allow the implementation of multistatism on board every ASW (Anti Submarine Warfare) assets. Used as a complement beside usual sonar functions for detection of submarines and global undersea situation awareness, this tool requests a high level of interoperability. Particularly dedicated to shallow waters, it will substantially improve the safety of escorted vessels and littoral approaches in areas where the maritime operations are now focused. Plan of presentation: Principles – Comparison to usual acoustic detection means, motivations, possible participants, levels and nature of cooperation (exchanges) Architectures – Implementations – Implications on systems, procedures, data and communication links Performances and advantages – Including acoustics and tactics (how to use MS, in which situation, what for...) Implementation – The different experimentations (FR, NATO), illustrations from FR sea trials Portable Raman Spectrometer for Maritime Security Applications Dr Janusz Smulko, Gdansk University of Technology, Poland A. Kwiatkowski M.Sc /M. Gnyba PhD/P. Wierzba PhD, Technical University of Gdansk, Poland Download Author Biography (PDF) The fast identification of explosives, narcotics and other chemicals carried on board of ships or transported in containers to the harbors is an important problem of maritime security. Raman spectroscopy is widely used for fast identification of various chemicals. Continuous progress in the field of photonics has resulted in commercial availability of low-power compact Raman spectrometers which can be integrated into portable systems. Such systems can be used by law enforcement personnel or first responders to identify solid and liquid chemical substances of concern in the scene. Compared to other analytical techniques, these systems obviate the need for any sample preparation, perform measurement nondestructively, without physical contact with the substance (e.g. through the plastic or glass vials), providing result up to a minutes. This paper will present a portable Raman spectrometer designed and built as well as discusses its operation and performance. The device uses separate modules of 785 nm and 355 nm lasers of class IIIB that work independently to reduce disturbances at the field measurements and to increase amount of investigated chemicals. The spectrometer is controlled by an embedded PC. Measurements can be made in Raman range up to ~3500 cm-1 using thermoelectrically cooled CCD sensor and synchronous detection of modulated signal to increase signal-to-noise ratio. The example results of chemical identifications show efficiency of the developed system. The data analysis considers influence of glass/plastic vials on efficiency of detection of selected chemical mixtures. Finally, possible improvements in the quality of identification of chemicals that can be encountered by military and law enforcement personnel of maritime authorities will be discussed.
