The application of acoustic ranging to the automatic control of a ground vehicle

G. T. Clemence; G. W. Hurlbut IEEE Transactions on Vehicular Technology, 1983

The use of acoustics is proposed as an alternative method to determine the position of a vehicle relative to the road or to other vehicles. Acoustic transducers mounted on the vehicle would range to passive targets along the side of the road or to other vehicles. The simplicity of the system indicates that it could offer potential advantages in cost ...

  • Conclusion: The New Acoustics

    What does the history of acoustics tell us about the discipline of physics and its transformations in the interwar period? What does it tell about its objects, its objectives, its practices, and its material and immaterial tools? As I argue in the introduction, the field of acoustics does not feature in our common understanding of "modern physics."

  • Notes

    At the end of the nineteenth century, acoustics was a science of musical sounds; the musically trained ear was the ultimate reference. Just a few decades into the twentieth century, acoustics had undergone a transformation from a scientific field based on the understanding of classical music to one guided by electrical engineering, with industrial and military applications. In this book, Roland Wittje traces this transition, from the late nineteenth- century work of Hermann Helmholtz to the militarized research of World War I and media technology in the 1930s. Wittje shows that physics in the early twentieth century was not only about relativity and atomic structure but encompassed a range of experimental, applied, and industrial research fields. The emergence of technical acoustics and electroacoustics illustrates a scientific field at the intersection of science and technology. Wittje starts with Helmholtz's and Rayleigh's work and its intersection with telegraphy and ear y wireless, and continues with the industrialization of acoustics during World War I, when sound measurement was automated and electrical engineering and radio took over the concept of noise. Researchers no longer appealed to the musically trained ear to understand sound but to the thinking and practices of electrical engineering. Finally, Wittje covers the demilitarization of acoustics during the Weimar Republic and its remilitarization at the beginning of the Third Reich. He shows how technical acoustics fit well with the Nazi dismissal of pure science, representing everything that "German Physics" under National Socialism should be: experimental, applied, and relevant to the military.

    "This invaluable book provides a comprehensive framework for the formulation and solution ofnumerous problems involving the radiation, reception, propagation, and scattering of electromagnetic and acoustic waves. Filled with original derivations and theorems, it includes the first rigorous development of plane-wave expansions for time-domain electromagnetic and acoustic fields. For the past 35 years, near-field measurement techniques have been confined to the frequency domain. Now, with the publication of this book, probe-corrected near-field measurement techniques have been extended to ultra-wide-band, short-pulse transmitting and receiving antennas and transducers. By combining unencumbered straightforward derivations with in-depth expositions of prerequisite material, the authors have created an invaluable resource for research scientists and engineers in electromagnetics and acoustics, and a definitive reference on plane-wave expansions and near-field measurements. Featured topics include: * An introduction to the basic electromagnetic and acoustic field equations * A rigorous development of time-domain and frequency-domain plane-wave representations * The formulation of time-domain, frequency-domain, and static planar near-field measurement techniques with and without probe-correction * Sampling theorems and computation schemes for time- domain and frequency-domain fields * Analytic-signal formulas that simplify the formulation and analysis of transient fields * Wave phenomena, such as ``electromagnetic missiles"" encountered only in the time domain * Definitive force and power relations for electromagnetic and acoustic fields and sources."

  • A Survey of Time Delay Estimation Performance Bounds

    In this paper we review performance bounds, as well as some current trends, in time delay estimation (TOE). Research over several decades reveals that a few key parameters determine TOE performance. The most basic are the signal-to- noise ratio (SNR), and the signal time-bandwidth (TB) product; larger values for each are desirable. The Cramér-Rao bound (CRR) reveals asymptotic maximum-likelihood estimation (MLE) behavior with respect to TB and SNR. At moderate to lower SNR, TOEs generally break down as ambiguities arise due to increased noise and the cross-correlation of the signal, causing the TOE to deviate (often quite sharply) away from the CRB. Because it is a local bound, the eRB does not indicate the threshold behavior, and Ziv-Zakai and other bounds have been developed to handle this. When TO is measured between multiple sensors, the coherence between them can fundamentally limit the result, an effect that occurs in acoustics due to the turbulent atmosphere. We discuss modifications to the classical bounds that accommodate the coherence loss, and reveal a threshold coherence phenomenon. When communications and other signals are utilized for TOE, they may have significant nuisance parameters, including carrier uncertainty, unknown symbols, as well as effects due to an unknown channel. Recent TDE performance limits reveal the effect of these parameters for various signal models, including the impact of diversity channels on TDE.

  • Science Goes to War: Warfare and the Industrialization of Acoustics

    World War I broke out on 28 July 1914 and lasted until 11 November 1918. It brought an end to the bourgeois and aristocratic world order of the Wilhelmine and Edwardian era. Though its main battles were carried out in Europe, World War I was a global war to the extent that it affected most of the world's population, including many people in the colonies of the European imperial powers.

    The auscultation method is an important diagnostic indicator for hemodynamic anomalies. Heart sound classification and analysis play an important role in the auscultative diagnosis. The term phonocardiography refers to the tracing technique of heart sounds and the recording of cardiac acoustics vibration by means of a microphone-transducer. Therefore, understanding the nature and source of this signal is important to give us a tendency for developing a competent tool for further analysis and processing, in order to enhance and optimize cardiac clinical diagnostic approach. This book gives the reader an inclusive view of the main aspects in phonocardiography signal processing.

  • Part III: The War Years

    Electrical engineering is a protean profession. Today the field embraces many disciplines that seem far removed from its roots in the telegraph, telephone, electric lamps, motors, and generators. To a remarkable extent, this chronicle of change and growth at a single institution is a capsule history of the discipline and profession of electrical engineering as it developed worldwide. Even when MIT was not leading the way, the department was usually quick to adapt to changing needs, goals, curricula, and research programs. What has remained constant throughout is the dynamic interaction of teaching and research, flexibility of administration, the interconnections with industrial progress and national priorities.The book's text and many photographs introduce readers to the renowned teachers and researchers who are still well known in engineering circles, among them: Vannevar Bush, Harold Hazen, Edward Bowles, Gordon Brown, Harold Edgerton, Ernst Guillemin, Arthur von Hippel, and Jay Forrester.The book covers the department's major areas of activity - electrical power systems, servomechanisms, circuit theory, communications theory, radar and microwaves (developed first at the famed Radiation Laboratory during World War II), insulation and dielectrics, electronics, acoustics, and computation. This rich history of accomplishments shows moreover that years before "Computer Science" was added to the department's name such pioneering results in computation and control as Vannevar Bush's Differential Analyzer, early cybernetic devices and numerically controlled servomechanisms, the Whirlwind computer, and the evolution of time-sharing computation had already been achieved.Karl Wildes has been associated with the Department of Electrical Engineering and Computer S cience since the 1920s, and is now Professor Emeritus.
