Book excerpt: Oak Ridge National Laboratory (ORNL) and Quantum Magnetics, Inc. (QM) are exploring novel landmine detection technologies. Technologies considered here include bioreporter bacteria, swept acoustic resonance, nuclear quadrupole resonance (NQR), and semiotic data fusion. Bioreporter bacteria look promising for third-world humanitarian applications; they are inexpensive, and deployment does not require high-tech methods. Swept acoustic resonance may be a useful adjunct to magnetometers in humanitarian demining. For military demining, NQR is a promising method for detecting explosive substances; of 50,000 substances that have been tested, none has an NQR signature that can be mistaken for RDX or TNT. For both military and commercial demining, sensor fusion entails two daunting tasks, identifying fusible features in both present-day and emerging technologies, and devising a fusion algorithm that runs in real-time on cheap hardware. Preliminary research in these areas is encouraging. A bioreporter bacterium for TNT detection is under development. Investigation has just started in swept acoustic resonance as an approach to a cheap mine detector for humanitarian use. Real-time wavelet processing appears to be a key to extending NQR bomb detection into mine detection, including TNT-based mines. Recent discoveries in semiotics may be the breakthrough that will lead to a robust fused detection scheme.
Book Synopsis Detection of Explosives and Landmines by : Hiltmar Schubert

This book was released on 2012-12-06 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: This ARW is the third NATO-sponsored workshop on Explosives Detection and Humanitarian Demining. The previous events were • Detection and Destruction of Anti-Personnel Landmines Moscow, 1997 • Explosives Detection and Decontamination of the Environment Prague, 1997. Over the last decade applied research in Humanitarian Demining has made progress to some extend, but according to the tremendous tasks of Demining and the lack of scientific methods for practical detection of explosive devices, research activities are still of the same importance than ever before. Concerning countermeasures against terrorism the detection of explosives is one of the keyfactors, but the practical applications are not sufficient solved. An international exchange of research results are therefore urgent, to find out the most promising measures for application. The coincidence of this ARW and the terrible disaster of New York and Washington may demonstrate the importance of this task. In consequence the explosive device detection technologies can make a major contribution to collective, family and individual security. In developed countries, these technologies provide a strong deterrent and preventative measure against terrorist threats. In less developed regions, they can improve individual, institutional and state security, lessening the insecurity that motivates many terrorists acts. The elimination of landmine threats is just one of many ways of achieving this. However our attempts to meet the extremely difficult technical challenges posed by landmine and UXO contamination are inevitably leading us to new technological approaches.
Book Synopsis Explosives Detection using Magnetic and Nuclear Resonance Techniques by : Jacques Fraissard
Download or read book Explosives Detection using Magnetic and Nuclear Resonance Techniques written by Jacques Fraissard and published by Springer Science & Business Media. This book was released on 2009-07-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear quadrupole resonance (NQR) a highly promising new technique for bulk explosives detection: relatively inexpensive, more compact than NMR, but with considerable selectivity. Since the NQR frequency is insensitive to long-range variations in composition, mixing explosives with other materials, such as the plasticizers in plastic explosives, makes no difference. The NQR signal strength varies linearly with the amount of explosive, and is independent of its distribution within the volume monitored. NQR spots explosive types in configurations missed by the X-ray imaging method. But if NQR is so good, why it is not used everywhere? Its main limitation is the low signal-to-noise ratio, particularly with the radio-frequency interference that exists in a field environment, NQR polarization being much weaker than that from an external magnetic field. The distinctive signatures are there, but are difficult to extract from the noise. In addition, the high selectivity is partly a disadvantage, as it is hard to build a multichannel system necessary to cover a wide range of target substances. Moreover, substances fully screened by metallic enclosures, etc. are difficult to detect. A workshop was held at St Petersburg in July 2008 in an attempt to solve these problems and make NQR the universal technique for the detection of bombs regardless of type. This book presents the essentials of the papers given there.
Book Synopsis Field Detection Technologies for Explosives by : Yin Sun
Download or read book Field Detection Technologies for Explosives written by Yin Sun and published by ILM Publications. This book was released on 2010 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field Detection Technologies For Explosives Explosives are historically the weapons that have been most frequently used against civilians by terrorist organisations. In the past few years, the use of explosives by terrorist groups has cost the lives of more people than the combination of all other attacks, including the use of weapons of mass destruction (chemical, biological and nuclear weapons). Early detection of these substances is one of the most effective ways to prevent attacks using explosives from occurring. Fast and reliable equipment to detect the presence of explosives and explosive devices is critical to fighting terrorism. Written in a style that makes complicated technologies easy to understand, this book covers the principles, instrumentation and applications of current technologies used to detect explosives in the field. Both trace detection technologies and bulk detection technologies are discussed. The section on trace detection technologies includes chapters on ion mobility spectrometry, piezoelectric sensors, chemiluminescence-based detectors, polymer-based technologies and mass spectrometry. It also discusses detection requirements, methodologies used for detector evaluation, and sampling technologies. The section on bulk detection contains chapters on x-ray, millimeter wave imaging, neutron and nuclear quadrupoie resonance technologies. This volume introduces the basic concepts of commonly used explosives detection technologies and is an essential resource for novice or more experienced personnel working in the explosives detection field as well as those with a general interest in this important subject. Features Discusses all aspects of commonly used field detection technologies. Reviews detection requirements and explosives sampling methods. Describes specific instruments used for field detection applications, such as at airports, harbours and border crossings. Includes a summary of common explosives and their important properties for easy reference. Provides an introduction to data fusion and receiver operating characteristic methods, both of which have recently received significant attention in the field of explosives detection. Book jacket.

Available in PDF, EPUB and Kindle. Book excerpt: This volume presents selected contributions from the “Advanced Research Workshop on Explosives Detection” hosted by the Department of Information Engineering of the University of Florence, Italy in 2018. The main goal of the workshop was to find out how Science for Peace and Security projects in the field of Explosives Detection contribute to the development and/or refinement of scientific and technical knowledge and competencies. The findings of the workshop, presented in the last section of the book, determine future actions and direction of the SPS Programme in the field of explosives detection and management.The NATO Science for Peace and Security (SPS) Programme, promotes dialogue and practical cooperation between NATO member states and partner nations based on scientific research, technological innovation and knowledge exchange. Several initiatives were launched in the field of explosive detection and clearance, as part of NATO’s enhanced role in the international fight against terrorism. Experts and scientists from NATO members and partner countries have been brought together in multi-year projects, within the framework of the SPS Programme, to cooperate in the scientific research in explosive detection field, developing new technologies and methods to be implemented in order to detect explosive substances in different contexts.
Book Synopsis Low Threshold Organic Semiconductor Lasers by : Yue Wang
Download or read book Low Threshold Organic Semiconductor Lasers written by Yue Wang and published by Springer Science & Business Media. This book was released on 2013-10-01 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on two areas - the development of miniature plastic lasers that can be powered by LEDs, and the application of these lasers as highly sensitive sensors for vapours of nitroaromatic explosives (e.g. TNT). Polymer lasers are extremely compact visible lasers; the research described in the thesis is groundbreaking, driving forward the technology and physical understanding to allow these lasers to be routinely pumped by a single high-power LED. A notable advance in the work is the demonstration of nanoimprinted polymer lasers, which exhibit the world's lowest pump threshold densities by two orders of magnitude. The thesis also advances the application of these compact, novel lasers as highly sensitive detectors of explosive vapours, demonstrating that rapid detection can be achieved when microporous polymers are used. This work also demonstrates a prototype CMOS-based microsystem sensor for explosive vapours, exploiting a new detection approach.
Book Synopsis Detecting Improvised Explosive Devices by : Christopher M. Benson
Download or read book Detecting Improvised Explosive Devices written by Christopher M. Benson and published by . This book was released on 2012 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a new defense strategy, the withdrawal of forces from Iraq and Afghanistan, and looming budget and personnel cuts, the United States has an opportunity to re-evaluate its counter-improvised explosive device (C-IED) strategies and develop enduring strategies to detect and mitigate IEDs in future conflict. IEDs are an enduring, global threat and the weapon of choice for insurgents, terrorists, and other adversaries wishing to oppose a technologically superior force. The United States has spent billions of dollars to develop technologies to detect IEDs, but those efforts have not significantly improved IED find rates. In fact, dogs, humans, and low-tech methods are the best detectors. To effectively detect and mitigate IEDs in the future, the United States must re-evaluate its strategy and export capabilities to its partners and allies to ensure they possess the capability to defeat IEDs within their areas of responsibility. This paper focuses on defeating the device, specifically ground-emplaced (buried or surface-laid) improvised explosive devices.

Book Synopsis Unexploded Ordnance Detection and Mitigation by : James Byrnes
Download or read book Unexploded Ordnance Detection and Mitigation written by James Byrnes and published by Springer Science & Business Media. This book was released on 2008-12-19 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapters in this volume were presented at the July–August 2008 NATO Advanced Study Institute on Unexploded Ordnance Detection and Mitigation. The conference was held at the beautiful Il Ciocco resort near Lucca, in the glorious Tuscany region of northern Italy. For the ninth time we gathered at this idyllic spot to explore and extend the reciprocity between mathematics and engineering. The dynamic interaction between world-renowned scientists from the usually disparate communities of pure mathematicians and applied scientists which occurred at our eight previous ASI’s continued at this meeting. The detection and neutralization of unexploded ordnance (UXO) has been of major concern for very many decades; at least since the First World war. UXO continues to be the subject of intensive research in many ?elds of science, incl- ing mathematics, signal processing (mainly radar and sonar) and chemistry. While today’s headlines emphasize the mayhem resulting from the placement of imp- vised explosive devices (IEDs), humanitarian landmine clearing continues to draw signi?cant global attention as well. In many countries of the world, landmines threaten the population and hinder reconstruction and fast, ef?cient utilization of large areas of the mined land in the aftermath of military con?icts.

Book Synopsis Detection of Buried Mines and Unexploded Ordnance (UXO). by :
Download or read book Detection of Buried Mines and Unexploded Ordnance (UXO). written by and published by . This book was released on 2007 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most military and commercial detectors sense the presence of metal casings or components of buried mines or explosive ordnance; however, this traditional approach to mine and unexploded ordnance (UXO) detection is prone to high false alarm rates. Explosive components, common to all mines and ordnance devices, offer a unique discriminator among buried objects. Two approaches to detect buried explosive devices directly are investigated: chemical trace detection, which relies on detecting either the vapor emanating from buried devices or the small explosive particles [and/or their explosive-related compounds (ERCs)] concentrated in the top soil, and radiation techniques, which uses radiation to probe beneath the earth's surface to provide bulk detection of buried explosive devices. This report describes the technology approaches and the current performance of each approach and discusses some promising new explosive detection technologies. It suggests that the Joint Unexploded Ordnance Coordination Office (JUXOCO) take a leadership role in establishing standards and protocols for reporting the results of field measurements in which trace analyses are used for detection of buried mines and ordnance and in sponsoring the development and maintenance of an open-sourced code to predict the variability of explosive detection in different environments.
Book Synopsis Low-Cost Simple Compact and Portable Ground-Penetrating Radar Prototype for Detecting Improvised Explosion Devices by : Krishnendu Raha
Download or read book Low-Cost Simple Compact and Portable Ground-Penetrating Radar Prototype for Detecting Improvised Explosion Devices written by Krishnendu Raha and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter presents the design and fabrication of a low-cost continuous-wave ground-penetrating radar for detecting improvised explosive devices buried in the soil for use of security forces. It is low cost and simple because it uses a single frequency (920 MHz) and is designed only for the detection of the buried target. The work presented includes designing of transmitter system module, receiver system module, antennas, power module, graphical user interface module, and making a prototype that is compact and portable. The chapter explains the concept and illustrates a method to enhance isolation between antennas, which is a very important parameter for the effective functioning of ground-penetrating radar. The presented method of enhancing isolation by cavity-backing a rectangular microstrip antenna and keeping them separated at an optimum gap yielded high isolation of 52.6 dB. The prototype radar, using the enhanced isolation antennas, demonstrates the capability to detect up to the depth of 65 cm for a circular steel target of radius 12.5 cm buried in loose semi-dry pebbled soil. The prototype radar is sensitive enough to detect a plastic box, a small bunch of wire, a book (paper) buried in soil and a wooden slab and a steel scale buried in a sandpit.
