Book Synopsis Aperture Synthesis for HF Radio Signals Propagated Via the F Layer of the Ionosphere by : John Thomas Lynch

Download or read book Aperture Synthesis for HF Radio Signals Propagated Via the F Layer of the Ionosphere written by John Thomas Lynch. This book was released on 1970. Available in PDF, EPUB and Kindle. Book excerpt: A portable high-frequency (HF) radio aperture up to 70 km in length was synthesized by receiving ionospherically propagated signals in a DC-3 airplane. By thus moving a small antenna rapidly over a long distance, a narrow receiving beam width (high azimuthal resolution) was achieved. It is believed that the synthetic aperture described here is the first in the world developed for HF, although the concept has been used successfully at microwave frequencies. (Author).

Book Synopsis Interferometry in Radioastronomy and Radar Techniques by : R. Wohlleben

Download or read book Interferometry in Radioastronomy and Radar Techniques written by R. Wohlleben. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: In recent years aperture synthesis and interferometry have become very powerful tools in radioastronomy. Investigation of distant galaxies, for example, have revealed structures with sizes of less than a kiloparsec. In general, the study of galaxies has benefited from the great power of these techniques. Radar applications have also dramatically increased their quality by using the interferometry principle. Tracking and airborne radar can now determine position and velocity of objects with a much higher accuracy. This book describes in the first six, short chapters the basics of interferometry and aperture synthesis. The following two, long chapters treat the aspects of radioastronomical interferometers and radar applications of interferometry in great detail. The text offers readers a very good opportunity to familiarize themselves with the mathematical background of these very complex techniques. For researchers and students in radioastronomy and electrical engineering.

Book excerpt: This open access book on the history of the National Radio Astronomy Observatory covers the scientific discoveries and technical innovations of late 20th century radio astronomy with particular attention to the people and institutions involved. The authors have made extensive use of the NRAO Archives, which contain an unparalleled collection of documents pertaining to the history of radio astronomy, including the institutional records of NRAO as well as the personal papers of many of the pioneers of U.S. radio astronomy. Technical details and extensive citations to original sources are given in notes for the more technical readers, but are not required for an understanding of the body of the book. This book is intended for an audience ranging from interested lay readers to professional researchers studying the scientific, technical, political, and cultural development of a new science, and how it changed the course of 20th century astronomy.
