| phased array testing basic theory: Fundamentals of Ultrasonic Phased Arrays Lester W. Schmerr Jr., 2014-08-13 This book describes in detail the physical and mathematical foundations of ultrasonic phased array measurements. The book uses linear systems theory to develop a comprehensive model of the signals and images that can be formed with phased arrays. Engineers working in the field of ultrasonic nondestructive evaluation (NDE) will find in this approach a wealth of information on how to design, optimize and interpret ultrasonic inspections with phased arrays. The fundamentals and models described in the book will also be of significant interest to other fields, including the medical ultrasound and seismology communities. A unique feature of this book is that it presents a unified theory of imaging with phased arrays that shows how common imaging methods such as the synthetic aperture focusing technique (SAFT), the total focusing method (TFM), and the physical optics far field inverse scattering (POFFIS) imaging method are all simplified versions of more fundamental and quantitative imaging approaches, called imaging measurement models. To enhance learning, this book first describes the fundamentals of phased array systems using 2-D models, so that the complex 3-D cases normally found in practice can be more easily understood. In addition to giving a detailed discussion of phased array systems, Fundamentals of Ultrasonic Phased Arrays also provides MATLAB® functions and scripts, allowing the reader to conduct simulations of ultrasonic phased array transducers and phased array systems with the latest modeling technology. |

| phased array testing basic theory: Structural Health Monitoring Damage Detection Systems for Aerospace Markus G. R. Sause, Elena Jasiūnienė, 2021-09-22 This open access book presents established methods of structural health monitoring (SHM) and discusses their technological merit in the current aerospace environment. While the aerospace industry aims for weight reduction to improve fuel efficiency, reduce environmental impact, and to decrease maintenance time and operating costs, aircraft structures are often designed and built heavier than required in order to accommodate unpredictable failure. A way to overcome this approach is the use of SHM systems to detect the presence of defects. This book covers all major contemporary aerospace-relevant SHM methods, from the basics of each method to the various defect types that SHM is required to detect to discussion of signal processing developments alongside considerations of aerospace safety requirements. It will be of interest to professionals in industry and academic researchers alike, as well as engineering students. This article/publication is based upon work from COST Action CA18203 (ODIN - http://odin-cost.com/), supported by COST (European Cooperation in Science and Technology). COST (European Cooperation in Science and Technology) is a funding agency for research and innovation networks.

| phased array testing basic theory: Aeroacoustic Measurements Thomas J. Mueller, 2013-11-27 During the past three decades, there has been a growing concern over the in crease in noise pollution that comes as a direct result of the increased volume of automobile traffic, high-speed trains, and larger aircraft. Additional sources of noise are commonly found in air handling equipment (such as fans and pro pellers) and a variety of machinery used in construction and manufacturing. A vast majority of these noise sources are the result of a given system's aero acoustic response, or sound generated by the interaction of a flow field with the given structure. While barriers are commonly used to shield communities from highway and train noise, and absorption materials are used to shield machinery noise, there is no way to shield communities near major airports from the noise gen erated by low-flying aircraft. Tens of millions of people worldwide are affected by this airport noise problem. In densely populated Europe, up to 15 % of the total population is strongly influenced by airport noise. Since the volume of air traffic will continue to grow, so too will the problem and the number of people involved. It is not surprising that many countries and communities have taken legal action to preserve the quality of life in these areas. As a result, the airlines, airports, manufacturers and governments are working together to set new standards for aircraft noise reduction. In order to establish realistic goals, the generation and propagation of acoustic sources must be better understood. |

| phased array testing basic theory: Fundamentals of Strategic Weapons James N. Constant, 2013-12-01 The purpose of this book is to provide graduate students, professional engineers, military officers, and weapons-systems planners with a comprehensive grounding in the technology, evolution, functions, costs, impacts on society, utility, and limi tations of modern strategic weapons systems. Since the subject is often left to the specialists, this work should introduce the general reader to the fundamentals of such systems in an informed manner. Nowadays the intense interaction of means and ends sym bolized by strategic weapons has stimulated a changing dis cipline in which new missile systems and the intricate logic of nuclear force and counterforce hold the stage alongside the truths of conflict, alliances, fears, games, and subtle gains and losses. Many readers with new personal interest or public responsibility in this complex field will require an overall guide to it. This book will not prepare the reader to become an expert in the vast subject of strategic weapons systems. It will, however, enable him to understand, evaluate, and form reasonable opinions about these systems, their capabilities and effective ness. The subject is dealt with more from the viewpoint of the user (investor) rather than the architect (systems engineer) and builder (design engineer). While the user will be concerned with both political as well as technical options which may be available to solve a problem, the systems and design engineers are concerned with analyzing and building technological weapons devices once their requirements are generally known. |

| phased array testing basic theory: Masters Theses in the Pure and Applied Sciences Wade H. Shafer, 2013-11-21 Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for lnformation and Numerica/ Data Analysis and Synthesis (C/NDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficia! to the academic and general scientific and technical community. After fi ve years of this joint undertaking we had concluded that it was in the interest of ali concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and App/ied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. Ali back issues can also be ordered from Plenum. We have reported in Volume 21 (thesis year 1976) a total of 10,586 theses titles from 25 Canadian and 219 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. |
