The third edition of this indispensable book in radio interferometry provides extensive updates to the second edition, including results and technical advances from the past decade; discussion of arrays that now span the full range of the radio part of the electromagnetic spectrum observable from the ground, 10 MHz to 1 THz; an analysis of factors that affect array speed; and an expanded discussion of digital signal-processing techniques and of scintillation phenomena and the effects of atmospheric water vapor on image distortion, among many other topics. With its comprehensiveness and detailed exposition of all aspects of the theory and practice of radio interferometry and synthesis imaging, this book has established itself as a standard reference in the field. It begins with an overview of the basic principles of radio astronomy, a short history of the development of radio interferometry, and an elementary discussion of the operation of an interferometer. From this foundation, it delves into the underlying relationships of interferometry, sets forth the coordinate systems and parameters to describe synthesis imaging, and examines configurations of antennas for multielement synthesis arrays. Various aspects of the design and response of receiving systems are discussed, as well as the special requirements of very-long-baseline interferometry (VLBI), image reconstruction, and recent developments in image enhancement techniques and astrometric observations. Also discussed are propagation effects in the media between the source and the observer, and radio interference, factors that limit performance. Related techniques are introduced, including intensity interferometry, optical interferometry, lunar occultations, tracking of satellites in Earth orbit, interferometry for remote Earth sensing, and holographic measurements of antenna surfaces. This book will benefit anyone who is interested in radio interferometry techniques for astronomy, astrometry, geodesy, or electrical engineering.Astronomy and Astrophysics Library,0941-7834Observations, AstronomicalAstronomy—ObservationsPhysicsAstronomy, Observations and Techniqueshttps://scigraph.springernature.com/ontologies/product-market-codes/P22014Applied and Technical Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P31000astronomyphysicscommunicationsradioengineeringObservations, Astronomical.Astronomy—Observations.Physics.Astronomy, Observations and Techniques.Applied and Technical Physics.520Thompson A.

Connecté à la fois à l’Orient, à l’Afrique subsaharienne et à la Méditerranée, le Maghreb islamique s’insère entre le viie et le xve siècle dans des connexions complexes qui donnent à ses ports un rôle croissant dans les échanges commerciaux, mais aussi plus largement dans la structuration de l’espace maghrébin et méditerranéen, à la fois comme pôles d’impulsion régionaux et interfaces entre des réseaux terrestres et maritimes. L’analyse des sources arabes et latines permet ainsi de montrer comment les acteurs politiques et économiques contribuent à faire évoluer ces réseaux commerciaux à différentes échelles, en premier lieu dans un espace centré sur les pays d’Islam, puis à partir du xie siècle dans une économie-monde en formation, connectant l’Afrique, l’Europe latine et l’Asie. Vinculado a la vez con Oriente, el África subsahariana y el Mediterráneo, el Magreb Islámico se inserta entre el siglo vii y el xv en redes complejas que otorgan a sus puertos un papel cada vez más importante en los intercambios comerciales. El análisis de las fuentes árabes y latinas permite mostrar cómo los actores políticos y económicos contribuyen a la evolución de estas redes, primero en los países islámicos, y luego, a partir del siglo xi, en una economía mundial en desarrollo que conecta África, la Europa latina y Asia. The Islamic Maghreb was connected to the Orient, Sub-Saharan Africa and the Mediterranean, and thus was integrated, between the 7th and the 15th centuries, into complex networks giving an increasing role to port cities, in the commercial exchanges but also, more broadly, in the structuration of space.
