Book Description
This book deals with the fundamentals of stellar interferometry with emphasis on aperture synthesis using sparse array of telescopes particularly at optical/IR wavelengths, the origin, properties, and optical effects of turbulence in the Earth's atmosphere, techniques developed to overcome image degradation. Studded with more than one hundred and fifty illustrations and tens of footnotes, it addresses the basic tricks of trade, current trend, motivation, methods, and path to future promise of true interferometry both from the ground and space. Also discussed are the technical challenge involved, such as beam transportation and recombination, detecting fringes using modern sensors, and image synthesis. Astronomical science that benefits from aperture synthesis imaging are highlighted as well.

Book Description
Microwave Scanning Antennas, Volume I: Apertures is a comprehensive account of phased arrays, multiple beam arrays, time domain and synthetic apertures, and adaptive antennas. Advances in continuous apertures and near field theory are discussed. Low noise and monopulse apertures, optical scanners, and large radomes are also covered, along with radio astronomy instruments and associated theory. Comprised of five chapters, this volume begins with an overview of aperture theory as well as aperture distributions and near field theory. The second and third chapters deal with mechanically steered and electronically scanned antennas, including monopulse antennas and optical scanners. The fourth chapter is devoted to radio astronomy instruments and techniques and encompasses both apertures and arrays, together with radio telescopes and antennas. The final chapter describes large radomes that are primarily used with aperture antennas. This book is intended for engineers who must understand narrow beam or high resolution antennas more deeply than from the system interfaces alone, and for undergraduate and graduate students in electronics who wish to complement their study of electromagnetics with the quantitative details of hardware applications.

Book Description
Fundamental Astronomy is a well-balanced, comprehensive introduction to classical and modern astronomy. While emphasizing both the astronomical concepts and the underlying physical principles, the text provides a sound basis for more profound studies in the astronomical sciences. This is the fifth edition of the successful undergraduate textbook and reference work. It has been extensively modernized and extended in the parts dealing with extragalactic astronomy and cosmology. You will also find augmented sections on the solar system and extrasolar planets as well as a new chapter on astrobiology. Long considered a standard text for physical science majors, Fundamental Astronomy is also an excellent reference work for dedicated amateur astronomers.

Book Description
Increasing information content is an important scientific problem in modern observation systems development. Radar, or microwave, imaging can be used for this purpose. The book provides an overview of the field and explains why a unified approach based on wave field processing techniques, including holographic and tomographic approaches, is necessary in high resolution radar design. It contains discussion of new areas in imaging radar theory, holographic radar, the questions of estimation and improving radar image quality, and finally various practical applications.

Book Description
Radio astronomy uses unique observational techniques and offers the only way to investigate many phenomena in the Universe. This book, by two founders of the field, presents both a clear introduction to radio telescopes and techniques, and a broad overview of the radio universe. The material in this new edition has been expanded and updated, reflecting the developments in the field over the last decade. New material reflects the increasing use of aperture synthesis and Very Long Baseline Interferometry, and the further exploitation of molecular spectral lines. A new chapter is devoted to the fundamentals of radiation and propagation theory. The second half of the book constitutes a review of radio observations of our Milky Way galaxy. Wide-ranging and clearly written, this book provides a thorough and up-to-date introduction to the subject for graduate students, and an invaluable overview for researchers turning to radio astronomy for the first time.
