This book was released on 1985 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the accuracy of an underwater acoustic positioning system in locating a sound source that transmits at unknown times in conditions in which the acoustic travel times between source and receivers fluctuate widely. The system uses three omnidirectional receivers. The accuracy of the system depends very much on the relative positions of these receivers. With well chosen relative receiver dispositions, the position of a sound source at 20 km range can be located within + or - 150 m, even with fluctuations in travel time of as high as + or - 100 ms.

Available in PDF, EPUB and Kindle. Book excerpt: This textbook covers all related communication technologies of underwater wireless communication, such as acoustic communication, optical communication, and magneto-inductive communication. After describing each technology, the authors relay their pros and cons, as it is essential to learn the underlying mechanism, advancements, and limitations of these techniques. Therefore, this book provides basics fundamentals of the three technologies, their advantages and disadvantages, and their applications. The authors also introduce research trends, pointing readers in the direction of research in the field of underwater wireless communication. The book is an essential textbook for undergraduate and graduate students in the field of underwater communications. The book is also useful as a reference to undergraduate engineering students, science students, and practicing engineers. The book includes end-of-chapter questions and numerical problems.

Download or read book The Effect of Source Speed on the Time Scale of Acoustic Fluctuations written by I. J. Rosenbaum and published by . This book was released on 1976 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The time scale of acoustic fluctuations has been found to depend on source speed for a shallow receiver-shallow sound source configuration in deep water off the coast of St. Croix, U.S. Virgin Islands. Measurements were made of a cw 135 hz source towed at 4 and 8 knots on a 5-mile tangential track through a point 7.5 miles from the receiving hydrophones. Using the correlation time, the time it takes an autocorrelogram to decay to (1/e) of its maximum value as a norm or standard, the higher source speed consistently gave rise to shorter correlation times. As the data integration period was increased from 5 seconds to 100 seconds, the measured correlation times increased as well, covering the range of 4 to 462 seconds for various source speed-receiver depth combinations. As a function of integration time, the difference between the correlation times at the two speeds became greater for a receiver located in the thermal layer than for a receiver beneath the layer.
