Book Description
This book is useful both for those who want to get initial information on the measurement of the antenna parameters, and for specialists directly involved in the experimental determination of the antenna parameters from the results of measuring the amplitude-phase distribution in the near zone of the antennas. Currently, the near-field method is the most common one for antenna measurements. In most books, an academic approach is given to the issue under consideration and it is difficult to use them for the direct organization of measurements. In many others, specific narrow issues are considered that are accessible to understanding only by highly qualified engineers/readers. The purpose of this book is to get rid of the above disadvantages by offering the reader a more accessible exposition and formulas by which appropriate computer programs can be written with minimal effort. The contents of this book allow interested specialists to be not only users of the near-field measuring facilities, but also help in understanding the principles of their work. This book is intended for engineers and specialists whose activities are related to experimental testing of radio characteristics of complex antenna systems, especially near-field measurements, and is also useful as a textbook for senior students in the field of “radioelectronics” and “radiophysics.”

Book Description
The measurement of the strength of radio frequency fields at high frequency and above has followed practices which are standard for the measurement of field strength at medium and low frequencies. Variability of measurements made in practical situations and a lack of reproducibility of measurements made under apparently identical conditions has prompted an investigation of equipment and methods used in the determinations. The field strength measurement study was undertaken to understand the nature of the problem and to develop techniques for more accurate determinations of field strength and more significant interpretation of measured data. A Stoddart Aircraft Company NM-52A field strength meter which has a frequency range of 375 to 1000 MHz was calibrated and evaluated using conventional methods. Instrumentation to extend the upper frequency limit of the testing procedure from 10 to 20 GHz was procured. Field strength meter antennas in the 2 to 4 GHz frequency range were tested and comparisons made with similar tests conducted by RADC. Methods of simplification of data acquisition and processing for use in aperture synthesis were investigated. (Author).

Book Description
The NAB Engineering Handbook provides detailed information on virtually every aspect of the broadcast chain, from news gathering, program production and postproduction through master control and distribution links to transmission, antennas, RF propagation, cable and satellite. Hot topics covered include HD Radio, HDTV, 2 GHz broadcast auxiliary services, EAS, workflow, metadata, digital asset management, advanced video and audio compression, audio and video over IP, and Internet broadcasting. A wide range of related topics that engineers and managers need to understand are also covered, including broadcast administration, FCC practices, technical standards, security, safety, disaster planning, facility planning, project management, and engineering management. Basic principles and the latest technologies and issues are all addressed by respected professionals with first-hand experience in the broadcast industry and manufacturing. This edition has been fully revised and updated, with 104 chapters and over 2000 pages. The Engineering Handbook provides the single most comprehensive and accessible resource available for engineers and others working in production, postproduction, networks, local stations, equipment manufacturing or any of the associated areas of radio and television.
