Accident records show that sooner or later hindrances near a waterway will be hit by ships, be it navigation marks, bridge structures, reefs or shallows. With this background modelling and analysis of ship collisions to bridge structures have an increasing importance as the basis for rational decision making in connection with planning, design and construction of bridges over navigable waters.

The publication Ship Collision Analysis, Proceedings of the 1998 International Symposium, presents the papers of international experts in ship collision analysis and structural design. The contributions give the state of the art and point to future development trends with in the focus areas.

Based on the experiences of the Department of Information Engineering of the University of Pisa and the Radar and Surveillance System (RaSS) national laboratory of the National Interuniversity Consortium of Telecommunication (CNIT), Radar Imaging for Maritime Observation presents the most recent results in radar imaging for maritime observation. The book explores both the areas of sea surface remote sensing and maritime surveillance providing key theoretical concepts of SAR and ISAR imaging and more advanced and ad-hoc techniques for applications in maritime scenarios. The book is organized in two sections. The first section discusses the fundamentals of standard SAR/ISAR processing and novel imaging techniques, such as Bistatic, Passive, and, 3D Interferometric ISAR. The second section focuses on the applications and results obtained by processing real data from maritime observations like SAR image processing for oil spill, detection in SAR images and fractal analysis. Useful to both beginners and experts in maritime observation, this book provides several examples of (mainly space-borne) radar imaging of maritime targets. Nevertheless, the same principles and techniques apply to the case of manned or unmanned carriers and to ground and air moving targets.

With the emergence of compressive sensing and sparse signal reconstruction, approaches to urban radar have shifted toward relaxed constraints on signal sampling schemes in time and space, and to effectively address logistic difficulties in data acquisition. Traditionally, these challenges have hindered high resolution imaging by restricting both bandwidth and aperture, and by imposing uniformity and bounds on sampling rates. Compressive Sensing for Urban Radar is the first book to focus on a hybrid of two key areas: compressive sensing and urban sensing. It explains how reliable imaging, tracking, and localization of indoor targets can be achieved using compressed observations that amount to a tiny percentage of the entire data volume. Capturing the latest and most important advances in the field, this state-of-the-art text: Covers both ground-based and airborne synthetic aperture radar (SAR) and uses different signal waveforms Demonstrates successful applications of compressive sensing for target detection and revealing building interiors Describes problems facing urban radar and highlights sparse reconstruction techniques applicable to urban environments Deals with both stationary and moving indoor targets in the presence of wall clutter and multipath exploitation Provides numerous supporting examples using real data and computational electromagnetic modeling Featuring 13 chapters written by leading researchers and experts, Compressive Sensing for Urban Radar is a useful and authoritative reference for radar engineers and defense contractors, as well as a seminal work for graduate students and academia.

August 1939 was a time of great flux. The fear of impending war fueled by the aggression of Nazi Germany forced many changes. Young people pursuing academic research were plunged into an entirely different kind of research and development. For Bernard Lovell, the war meant involvement in one of the most vital research projects of the war-radar. Echoes of War: The Story of H2S Radar presents a passionate first-hand account of the development of the Home Sweet Home (H2S) radar systems during World War II. The book provides numerous personal insights into the scientific culture of wartime Britain and details the many personal sacrifices, setbacks, and eventual triumphs made by those actively involved. Bernard Lovell began his work on airborne interception radar in Taffy Bowen's airborne radar group. He was involved in the initial development of the application of the 10 centimeter cavity magnetron to airborne radar that revolutionized radar systems. In the autumn of 1941, the failure of Bomber Command to locate its target over the cloudy skies of Europe prompted the formation of a new group to develop a blind bombing system. Led by Lovell, this group developed the H2S radar system to identify towns and other targets at night or during heavy cloud cover. H2S first saw operational use with the Pathfinder Squadrons in the attack on Hamburg during the night of January 30-31, 1943. Two months later, modified H2S units installed in Coastal Command aircraft operating over the Bay of Biscay had a dramatic tactical effect on the air war against U-boats. The tide had begun to turn. In this fascinating chronicle of the H2S radar project, Sir Bernard Lovell recreates the feel and mood of the wartime years.

This book presents the current history of United States military strategy in Afghanistan as an example of dysfunctional policy discourse among the nation's elites. The legitimacy of a country's military strategy can become a subject of intense public debate and doubt, especially in prolonged conflicts. Arguments typically hinge on disagreements about the values at stake, the consequences of action or inaction, and the authority of those responsible for the plan. As the US entered its second decade at war in Afghanistan, political and military leaders struggled to explain the ends and means of their strategy through internal policy debates, the promotion of counterinsurgency doctrine, and day-to-day accounts of the war's progress. Military Strategy as Public Discourse considers recent US strategy in Afghanistan as a form of valid and equitable public discussion among those with the ability to affect outcomes. The work examines the dominant forms of discourse used by the various groups of elites who make and execute strategy, and considers how representations of these forms of discourse in news media shapes elite understanding of the purpose of US efforts in wars of choice. The book proposes how policy-makers should address the problems of public discourse on war, which tends to exclude or marginalize relevant elites and focus on narrow questions of validity. This book will be of much interest to students of strategic studies, US foreign policy, and security studies in general.

There has long been a strong collaboration between geologists and archaeologists, and the sub-field of geoarchaeology is well developed as a discipline in its own right. This book now bridges the gap between those fields and the geophysical technique of ground-penetrating radar (GPR), which allows for three-dimensional analysis of the ground to visualize both geological and archaeological materials. This method has the ability to produce images of the ground that display complex packages of materials, and allows researchers to integrate sedimentary units, soils and associated archaeological features in ways not possible using standard excavation techniques. The ability of GPR to visualize all these buried units can help archaeologists place ancient people within the landscapes and environments of their time, and understand their burial and preservation phenomena in three-dimensions. Readership: Advanced students in archaeology and geoarchaeology, as well as practicing archaeologists with an interest in GPS techniques.
