Book excerpt: In the last ten years, vast improvements in technology and instrumentation have allowed radio astronomy to go beyond the stage where its measurements were principally of interest to pure science (astronomy, astrophysics, cosmology, etc.) to a stage today where such measurements have important practical application in the fields of communications, radar, and antenna systems. This report covers the application of extraterrestrial radio sources, whose emission properties (flux density, spectrum, celestial position, angular size, etc.) have been firmly established by careful radio-astronomical observations, to the determination of antenna parameters. The extraterrestrial radio sources whose properties are presented are the sun, the moon, and the strong discrete (celestial) radio sources. The areas of application discussed in detail are the determination of antenna gain, effective area, and aperture efficiency and the measurement of the power pattern of an antenna. Another application briefly discussed is the measurement of effective radiated power from satellites. (Author).

Download or read book Literature 1969, Part 2 written by Siegfried Böhme and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy and Astrophysics Abstracts, which appears in semi-annual volumes, is devoted to the re cording, summarizing and indexing of astronomical publications throughout the world. It aims to pre sent a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly issued abstracting journals, compared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume 2 contains literature published in 1969 and received before March 15, 1970; some older lite rature which was received late and which is not recorded in Volume 1 is also included. The authors of papers who have sent us abstracts on request have effectively contributed to the suc cess of our service. We should like to express our gratitude to them. We acknowledge with thanks con tributions to this volume by Dr. J. Bou~a, who surveyed journals and publications in Czech language and supplied us with abstracts in English, by Dr. B. Onderlicka, Brno, for providing English ab stracts of Russian papers, and by the Commonwealth Scientific and Industrial Research Organization (C.S.I.R.O.), Sydney, for providing titles and abstracts of papers on radio astronomy.

Book excerpt: A 2000-ft circular array antenna using radio stars as sources has recently been constructed and tested at Sudbury, Massachusetts. The array operates at 5.0 to 7.5 MHz and can electronically scan a 3-deg main beam with 8 dB side lobes. It is designed with a flat transfer function to experimentally examine data processing techniques using restoration and enhancement procedures. The report gives the complete description and theory of the array as well as the results of the calibration and testing. (Author).

This book was released on 2007-07-16 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio astronomers have developed techniques of calibration of large reflector antennas with radio astronomical methods, but these have not been comprehensively described. This text aims to fill this gap, taking a practical approach to the characterisation of antennas. All calculations and results in the form of tables and figures have been made with Mathematica by Wolfram Research. The reader can use the procedures for the implementation of his own input data.

This book was released on 1976 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physics of microwave-burst emission is briefly examined to give the rationale for investigating polarization spectra. The instruments used to carry out the 9.4 GHz and 7 GHz circular-polarization measurements and the 5 GHz Stokes-parameter measurements are described. A survey of the August 1972 to December 1973 period produced a table of 45 bursts, from which some limited results were obtained. About 75 to 80 percent of all bursts are circularly polarized, with varying polarization over the 5 to 9.4 GHz range. For most bursts where the circular polarization pc increases toward the upper or lower end of the 5 to 9.4 GHz range, the total intensity I also increases in that direction. The few bursts having a pc sense reversal in the 5 to 9.4 GHz range also have a spectral maximum of I at roughly the same frequency. Some simplified explanations of the results are presented.
