The book "Interferometry and Synthesis in Radio Astronomy" by A. Richard Thompson, James M. Moran, and George W. Swenson Jr. is a comprehensive and updated edition of a classic text in the field of radio astronomy. The third edition, published by Springer International Publishing, covers the principles and applications of interferometry and synthesis in radio astronomy, making it a valuable resource for both graduate students and professionals. The book begins with a historical introduction, highlighting early radio observations and the development of interferometers to improve angular resolution. It then delves into the theory of interferometry and synthesis imaging, including the Fourier Transform, convolution, and the measurement equation. The text also discusses the geometry of interferometers, multi-element interferometer systems, and the response of electronic receiver systems. The new edition includes significant updates on digital signal processing, Very Long Baseline Interferometry (VLBI), calibration and imaging techniques, and the impact of atmospheric conditions on interferometric measurements. The authors also address the challenges posed by the fluctuating index of refraction in the propagation medium and the need for real-time corrections in large arrays. Overall, the book is well-structured, with detailed mathematical derivations, extensive references, and a comprehensive index. It is available as open access, making it freely accessible to anyone interested in the field. The reviewer, Jacob W. M. Baars, from the Max-Planck-Institut für Radioastronomie, praises the book for its clarity and depth, making it an invaluable resource for anyone working in radio astronomy.The book "Interferometry and Synthesis in Radio Astronomy" by A.
