Editorial Reviews
Product Description
Confidently predict receiver system noise temperature using the techniques developed for NASA-JPL's Deep Space Network techniques presented, for the first time, in this groundbreaking resource. The book shows you how to analyze, design, measure and accurately evaluate the many detailed elements comprising noise temperature. After a thorough introductory overview, you delve into reflector performance issues, including material conductivity, perforations, protective coatings, the effects of terrestrial weather, and the influence of the Earth's Sun.
This in-depth reference covers mismatch error equations, in terms of both reflection coefficient magnitudes and VSWRs. Moreover, you find expert guidance in calibrating system noise temperature and antenna efficiency. The book includes easy-to-use formulas that enable you to calculate noise temperature of solid metallic reflector surfaces and of leaks in perforated plates or wire grids. What's more, you get an invaluable tutorial on using S- parameters to predict noise temperature of multiports.
