Produktinformationen zu „Interferometry and Synthesis in Radio Astronomy “
Radio telescopes have the potential of recording images in the universe at a resolution nearly 1,000 times higher than the Hubble Space telescope. To attain this resolution, astronomers rely on a technology called Very Long Baseline Interferometry (VLBI). With the launch of the first VLBI satellite, Very Long Baseline Array has now come into actual operation. This, as well as other developments over the last 10 years, has increased the need for an up-to-date technical reference in radio astronomy. The first edition of this title was seen as the standard reference on the subject and this edition provides a comprehensive account today's techniques used in interferometry and radio astronomy.
Klappentext zu „Interferometry and Synthesis in Radio Astronomy “
Comprehensive, authoritative coverage of interferometric techniques for radio astronomyIn 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.
