Найти книгу: "Interferometry and Synthesis in Radio Astronomy"

Comprehensive, authoritative coverage of interferometric techniques for radio astronomy In this Second Edition of Interferometry and Synthesis in Radio Astronomy, three leading figures in the development of large imaging arrays, including very-long-baseline interferometry (VLBI), describe and explain the technology that provides images of the universe with an angular resolution as fine as 1/20,000 of an arcsecond. This comprehensive volume begins with a historical review followed by detailed coverage of the theory of interferometry and synthesis imaging, analysis of interferometer response, geometrical relationships, polarimetry, antennas, and arrays. Discussion of the receiving system continues with analysis of the response to signals and noise, analog design requirements, and digital signal processing. The authors detail special requirements of VLBI including atomic frequency standards, broadband recording systems, and antennas in orbit. Further major topics include: * Calibration of data and synthesis of images * Image enhancement using nonlinear algorithms * Techniques for astrometry and geodesy * Propagation in the neutral atmosphere and ionized media * Radio interference * Related techniques: intensity interferometry, moon occultations, antenna holography, and optical interferometry Interferometry and Synthesis in Radio Astronomy, Second Edition is comprehensive in that it provides an excellent overview of most radio astronomical instrumentation and techniques.

Астрономическая энциклопедия.Книга известного популяризатора астрономии Патрика Моора.Много фотографий,имеется алфавитный указатель. The new Philip's Astronomy Encyclopedia is one of the most comprehensive, authoritative and accessible books on astronomy. In more than 3000 alphabetically organized articles and over 500 photographs and diagrams, it covers everything and everyone from the Anglo-Australian Observatory to Fritz Zwicky. Its 464 pages include a host of major articles on subjects such as our Galaxy, the Sun and planets, optical and radio telescopes, stars, black holes, astrophysics, observatories, astronomical photography, space programmes, the constellations and famous astronomers. Supporting these articles are shorter entries on planetary features and satellites, asteroids, observational techniques, comets, satellite launchers, meteros, and subjects as diverse as life in the Universe and the structure of meteorites. Scores of tables list the brightest stars in the major constellations, annual meteor showers, major variable stars, dwarf stars, energy production processes in the Sun, and other relevant data. Philip's Astronomy Encyclopedia is written by more than 100 leading astronomers from the world's universities and observatories, each an expert in a specialized field of knowledge. They have produced an up-to-date and reliable popular reference work for 2001 and beyond.
