Available in PDF, EPUB and Kindle. Book excerpt: Existing experimental evidence is shown to be consistent with the idea that auroral backscatter arises from turbulent fluctuations of electron density as described by a Kolmogoroff spectrum. An inner scale of turbulence of one meter is shown to be consistent with the experimental data. It is further shown that the scatter cross section for frequencies greater than 1000 Mc cannot be accurately predicted. A brief summary of an analysis of auroral backscatter amplitude distribution is presented. Occasionally Rice type amplitude distributions are obtained at 49.7 Mc. These distributions admit of only one explanation - that on occasion, over relatively large regions and for intervals of only a few minutes, the electron density in the auroral ionosphere is in excess of 2 x 10 to the 7th power electrons per cubic centimeter.

This book was released on 1964 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes research on the Effects of the Aurora on Radio Wave Propagation. The research included a detailed theoretical study of the generation of synchrotron noise by auroral electrons spiralling in the earth's magnetic field. Experiments were conducted to detect iongyro modulation on radar returns from field aligned irregularities such as those associated with the aurora. A model of auroral radar reflections is discussed which hypothesizes acoustic waves excited by current streams which flow in the ionization enhanced regions at the base of auroral forms. A study was made of the effects on radio wave propagation of high velocity streams of electrons such as those in the solar wind. (Author).

Book excerpt: A comprehensive & illuminating history of this little-understood, but surprisingly significant scientific activity. Quite rigorous & systematic in its methodology, the book explores the development of the radar astronomy specialty in the larger community of scientists. More than just discussing the development of this field, however, the author uses planetary radar astronomy as a vehicle for understanding larger issues relative to the planning & execution of "big science" by the Fed. government. Sources, interviews, technical essay, abbreviations, & index.

Download or read book The Radio Noise Spectrum written by Donald Howard Menzel and published by Harvard University Press. This book was released on 1960 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This modern era has had many names: the golden age, the machine age, the atomic age, the electronic age, and so on. One further title, hitherto unpublicized, it eminently deserves: the age of noise. Man has compounded the natural noise that preceded his existence on the earth until no point on this globe is free from it. Even in the desert's hush, radio waves pervade the air and provide a source of potential noise. The shorter waves escape from the earth and fill interplanetary space with the mingled clamor of FM, TV, radar, and other insistent voices. This book deals with the important problem of radio noise, its sources, whether manmade or natural, over the known range of frequencies. Certain of these contributions will interest the communicator, enabling him to estimate the potential interference from various types of sources. Other contributions deal mainly with scientific problems, such as the origins and significance of certain characteristic noise radiations. The contributors to this book are experts on the various phases of radio noise. The individual chapters derive from papers presented at a Conference on Radio Noise, held at Harvard College Observatory, April 22, 1958.
