The Paraboloidal Reflector Antenna in Radio Astronomy and Communication
Author: Jacob W. M. BaarsPublisher: Springer Science & Business Media
ISBN: 0387697349
Category : Science
Languages : en
Pages : 270
Book Description
Radio astronomers have developed techniques of calibration of large reflector antennas with radio astronomical methods, but these have not been comprehensively described. This text aims to fill this gap, taking a practical approach to the characterisation of antennas. All calculations and results in the form of tables and figures have been made with Mathematica by Wolfram Research. The reader can use the procedures for the implementation of his own input data.

Essential Radio Astronomy

ISBN: 069113779X
Category : Science
Languages : en
Pages : 376
Book Description
The ideal text for a one-semester course in radio astronomy Essential Radio Astronomy is the only textbook on the subject specifically designed for a one-semester introductory course for advanced undergraduates or graduate students in astronomy and astrophysics. It starts from first principles in order to fill gaps in students' backgrounds, make teaching easier for professors who are not expert radio astronomers, and provide a useful reference to the essential equations used by practitioners. This unique textbook reflects the fact that students of multiwavelength astronomy typically can afford to spend only one semester studying the observational techniques particular to each wavelength band. Essential Radio Astronomy presents only the most crucial concepts—succinctly and accessibly. It covers the general principles behind radio telescopes, receivers, and digital backends without getting bogged down in engineering details. Emphasizing the physical processes in radio sources, the book's approach is shaped by the view that radio astrophysics owes more to thermodynamics than electromagnetism. Proven in the classroom and generously illustrated throughout, Essential Radio Astronomy is an invaluable resource for students and researchers alike. The only textbook specifically designed for a one-semester course in radio astronomy Starts from first principles Makes teaching easier for astronomy professors who are not expert radio astronomers Emphasizes the physical processes in radio sources Covers the principles behind radio telescopes and receivers Provides the essential equations and fundamental constants used by practitioners Supplementary website includes lecture notes, problem sets, exams, and links to interactive demonstrations An online illustration package is available to professors

Pages : 772
Book Description
This book addresses a broad range of topics on antennas for space applications. First, it introduces the fundamental methodologies of space antenna design, modelling and analysis as well as the state-of-the-art and anticipated future technological developments. Each of the topics discussed are specialized and contextualized to the space sector. Furthermore, case studies are also provided to demonstrate the design and implementation of antennas in actual applications. Second, the authors present a detailed review of antenna designs for some popular applications such as satellite communications, space-borne synthetic aperture radar (SAR), Global Navigation Satellite Systems (GNSS) receivers, science instruments, radio astronomy, small satellites, and deep-space applications. Finally it presents the reader with a comprehensive path from space antenna development basics to specific individual applications. Key Features: Presents a detailed review of antenna designs for applications such as satellite communications, space-borne SAR, GNSS receivers, science instruments, small satellites, radio astronomy, deep-space applications Addresses the space antenna development from different angles, including electromagnetic, thermal and mechanical design strategies required for space qualification Includes numerous case studies to demonstrate how to design and implement antennas in practical scenarios Offers both an introduction for students in the field and an in-depth reference for antenna engineers who develop space antennas This book serves as an excellent reference for researchers, professionals and graduate students in the fields of antennas and propagation, electromagnetics, RF/microwave/millimetrewave systems, satellite communications, radars, satellite remote sensing, satellite navigation and spacecraft system engineering, It also aids engineers technical managers and professionals working on antenna and RF designs. Marketing and business people in satellites, wireless, and electronics area who want to acquire a basic understanding of the technology will also find this book of interest.

Apertures
Author: R. C. HansenPublisher: Academic Press
ISBN: 1483260631
Category : Technology & Engineering
Languages : en
Pages : 463
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
An important historical look at the space program's evolvingtelecommunications systems Large Antennas of the Deep Space Network traces the development ofthe antennas of NASA's Deep Space Network (DSN) from the network'sinception in 1958 to the present. It details the evolution of thelarge parabolic dish antennas, from the initial 26-m operation atL-band (960 MHz) through the current Ka-band (32 GHz) systems.Primarily used for telecommunications, these antennas also supportradar and radio astronomy observations in the exploration of thesolar system and the universe. In addition, the author also offersthorough treatment of the analytical and measurement techniquesused in design and performance assessment. Large Antennas of the Deep Space Network represents a vitaladdition to the literature in that it includes NASA-funded researchthat significantly impacts on deep space telecommunications. Partof the prestigious JPL Deep Space Communications and NavigationSeries, it captures fundamental principles and practices developedduring decades of deep space exploration, providing informationthat will enable antenna professionals to replicate radiofrequencies and optics designs. Designed as an introduction for students in the field as well as areference for advanced practitioners, the text assumes a basicfamiliarity with engineering and mathematical concepts andtechnical terms. The Deep Space Communications and Navigation Series is authored byscientists and engineers with extensive experience in astronautics,communications, and related fields. It lays the foundation forinnovation in the areas of deep space navigation and communicationsby disseminating state-of-the-art knowledge in key technologies.
