Microwave Radiometer Systems: Design and Analysis, Second Edition

Written by leading experts in industry and academia, this authoritative resource offers you a solid understanding of radiometer systems and shows you how to design a system based on given specifications, taking into account both technical aspects and geophysical realities. The book provides you with a complete explanation of radiometer sensitivity, and describes the concept of absolute accuracy and it's associated problems. The four major radiometer principles - total power, Dicke, noise-injection, and correlation - are presented in detail and their sensitivities are derived from the basic sensitivity formula provided in the book. Additionally, you find detailed review of the DTU noise-injection radiometer system. This practical reference covers radiometer receivers on a block diagram level, helping you determine whether to use direct- or super-heterodyne receivers and describing how to a combine double sideband or single sideband mixer operation with a microwave preamplifier. The book introduces the basic concept of aperture synthesis, explaining the benefits of using it for remote sensing. Moreover, you gain a thorough understanding of synthetic aperture radiometers and are provided with real-world examples, including the ESTAR and HYDROSTAR sensors. This comprehensive book also covers the relationships between swathwidth, footprint, integration time, sensitivity, and frequency for satellite born, real aperture imaging systems.
