With the guidance of this book, readers will gain unprecedented insight into all of the major topics needed to understand how to improve a ground station's receiving capability. Low-Noise Systems in the Deep Space Network provides:
A description of all internal and external noise elements
A complete analysis of ruby maser microwave preamplifiers and closed-cycle refrigerators
A comprehensive discussion of high electron mobility transistors (HEMT), including theory, operation, calibration, noise modeling, and characterization
A look at external noise and changing atmospheric conditions
An overview of antenna gain
All noise contributions in the front end are detailed in their measurement and calibration, with an emphasis on achieving maximum accuracy and precision. Each step is analyzed with mathematical rigor, so that the logic trail can be followed throughout. Conversely, the author also provides the overall summary of measurements, error analyses, and statistical results. The book is complemented with copious photographs, diagrams, graphs, and tables; an extensive list of acronyms and abbreviations; cross-references; and an extended list of equations brought together compactly for easy reference. It is an invaluable resource for designers and operators of communications systems, radio- and radar-astronomy stations, space-research facilities, and interferometry observatories. It is also suitable for a range of scientists, engineers, and management personnel, and advanced undergraduate and graduate students in engineering and mathematics.
MacGregor S. Reid, PhD, worked at the Jet Propulsion Laboratory (JPL) from 1969 until his retirement in 1998. For the last ten years of his career, he was technical executive assistant to the director. He served a three-year term as vice president of the American Institute of Aeronautics and Astronautics (AIAA), Washington, D.C. Dr. Reid was formation chairman of the International Organization for Standardization (ISO) Subcommittee on Space Systems and Operations for nine years, and he represented the United States on ISO's Committee on Aircraft and Space Operations for twelve years. He has served on many advisory committees, both nationally and internationally, and he is the author of more than eighty publications in the technical literature, three of which have won awards. In recognition of his international work, an asteroid was named after Dr. Reid in 1998 (6894 MacReid). He was awarded medals from AIAA and NASA, and six monetary awards from NASA for the invention of new technology.
