Interferometry And Synthesis In Radio Astronomy 2e
RRP $397.99
<b>Comprehensive, authoritative coverage of interferometric techniques for radio astronomy</b> <p> In this Second Edition of <i>Interferometry and Synthesis in Radio Astronomy</i>, 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. <p> 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. <p> The authors detail special requirements of VLBI including atomic frequency standards, broadband recording systems, and antennas in orbit. Further major topics include: <ul> <li>Calibration of data and synthesis of images <li>Image enhancement using nonlinear algorithms <li>Techniques for astrometry and geodesy <li>Propagation in the neutral atmosphere and ionized media <li>Radio interference <li>Related techniques: intensity interferometry, moon occultations, antenna holography, and optical interferometry </ul> <p> <i>Interferometry and Synthesis in Radio Astronomy, Second Edition</i> is comprehensive in that it provides an excellent overview of most radio astronomical instrumentation and techniques.

Johannes Kepler was a key figure in the scientific revolution of the 17th century and this in-depth biography delves into he life and works of the man whose laws of planetary motion became one of the bed rocks of Newton's theory of universal gravitation.
Image Processing Techniques In Astronomy
RRP $32.99
The primary inducement for organizing an international Conference on 'Image Processing Techniques in_Astronomy' was the fact that the recording microdensitometer VAMP ('Vol Automatische Micro Photometer') of the Utrecht Astronomical Institute was operative for a few years. The necessity of comparing the in- strument and its performance with similar instruments nowadays available at many other institutes, was stimulating enough to organize a meeting on the above subject. It took place in Utrecht on March 25, 26 and 27, 1975. The Scientific Organizing Committee consisted of J. Borgman (Groningen), R.B. Dunn (Sacramento Peak), H. Elsasser (Heidelberg), L.D. de Feiter, T. de Groot, J.R.W. Heintze, C. de Jager, H. Nieuwenhuijzen (Utrecht) and W. Wiskott (Geneve). About 175 scientists from 14 countries participated in the meeting which appeared to be successful and offered a good opportunity of exchanging information and comparing experiences. The VAMP was bought with financial support of the Utrecht University and the Netherlands Foundation for Scientific Research (Z.W.O.). The conference was organized with financial support from The Netherlands Ministry of Science and Education, The European Southern Observatory, The Leids Kerkhoven-Bosscha Fonds, The Astronomical Institute of Utrecht, to which Institutes and Organisations we express our sincere gratitude.
