Providing a definitive history of the formative years of radio astronomy, this book is invaluable for historians of science, scientists and engineers. The whole of worldwide radio and radar astronomy is covered, beginning with the discoveries by Jansky and Reber of cosmic noise before World War II, through the wartime detections of solar noise, the discovery of radio stars, lunar and meteor radar experiments, the detection of the hydrogen spectral line, to the discoveries of Hey, Ryle, Lovell and Pawsey in the decade following the war, revealing an entirely different sky from that of visual astronomy. Using contemporary literature, correspondence and photographs, the book tells the story of the people who shaped the intellectual, technical, and social aspects of the field now known as radio astronomy. The book features quotes from over a hundred interviews with pioneering radio astronomers, giving fascinating insights into the development of radio astronomy. Woodruff T. Sullivan III has been awarded the 2012 Leroy E. Doggett Prize for Historical Astronomy.

For a physicist, "noise" is not just about sounds, but refers to any random physical process that blurs measurements, and in so doing stands in the way of scientific knowledge. This book deals with the most common types of noise, their properties, and some of their unexpected virtues. The text explains the most useful mathematical concepts related to noise. Finally, the book aims at making this subject more widely known and to stimulate the interest for its study in young physicists.

Listening across millennia, a cultural historian explores the process by which noise today has become as powerfully metaphorical--and intriguing--as the original Babel. When did the "silent deeps" become cacophonous and galaxies begin to swim in a sea of cosmic noise? Why do we think that noises have colors and that colors can be loud? How loud is too loud, and says who? Attending, as ears do, to a surround of sounds at once physical and political, Hillel Schwartz listens across millennia for changes in the Western experience and understanding of noise. From the uproarious junior gods of Babylonian epics to crying infants heard over baby monitors, from doubly mythic Echo to amplifier feedback, from shouts frozen in Rabelaisian air to the squawk of loudspeakers and the static of shortwave radio, Making Noise follows "unwanted sound" on its surprisingly revealing path through terrains domestic and industrial, urban and rural, legal and religious, musical and medical, poetic and scientific. At every stage, readers can hear the cultural reverberations of the historical soundwork of actresses, admen, anthropologists, astronomers, builders, composers, dentists, economists, engineers, filmmakers, firemen, grammar school teachers, jailers, nurses, oceanographers, pastors, philosophers, poets, psychologists, and the writers of children's books. Drawing upon such diverse sources as the archives of antinoise activists and radio advertisers, catalogs of fireworks and dental drills, letters and daybooks of physicists and physicians, military manuals and training films, travel diaries and civil defense pamphlets, as well as museum collections of bells, ear trumpets, megaphones, sirens, stethoscopes, and street organs, Schwartz traces the process by which noise today has become as powerfully metaphorical as the original Babel. Endnotes and bibliography are not included in the physical book but are available online at the MIT Press Web site.

This cutting-edge resource introduces the basic concepts of passive bistatic radar, such as bistatic geometry, bistatic radar equation and analysis of different illuminating signals. These techniques, although known for almost a century, have not been developed intensively for decades, mainly due to technical limitations, but today, the passive radar concept can be realized in practice, and is of great interest for military and civilian users. This book provides insight into understanding the potential and limitations of passive radar systems, as well as the differences between signal processing in active and passive radar. Each of the signal processing stages typically applied in passive radar is described, including digital beamforming, clutter removal, target detection, localization and tracking. These concepts are illustrated with both simulated and measured data along with examples of passive radar systems. Correlation processing, which is crucial for passive radar operation, is presented, as well as practical approaches for calculating the cross-ambiguity function. The problems of range and velocity-cell migration are also introduced. The book analyzes and compares different antenna array geometries to show readers the appropriate solution for a particular scenario of passive radar. Cartesian tracking is also presented, based on the extended Kalman filter. Parallel and sequential updating approaches are introduced and compared. These concepts are illustrated with both simulated and measured data along with examples of passive radar systems, making this book useful for both novice and advanced practitioners.
