Available in PDF, EPUB and Kindle. Book excerpt: Thoroughly revising and updating an Artech House classic from 1989, this authoritative resource offers you a comprehensive and current 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 second edition contains a wealth of new material, including coverage of two of today's hottest microwave radiometry topics - polarimetric measurements and aperture synthesis. 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 book was released on 2018-07 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-spatial-resolution microwave radiometer sensing from space with reasonable swath widths and revisit times favors large aperture systems. However, with traditional precision antenna design, the size and weight requirements for such systems are in conflict with the need to emphasize small launch vehicles. This paper describes tradeoffs between the science requirements, basic operational parameters, and expected sensor performance for selected satellite radiometer concepts utilizing novel lightweight compactly packaged real apertures. Antenna, feed, and radiometer subsystem design and calibration are presented. Preliminary results show that novel lightweight real aperture coupled with state-of-the-art radiometer designs are compatible with small launch systems, and hold promise for high-resolution earth science measurements of sea ice, precipitation, soil moisture, sea surface temperature, and ocean wind speeds.

Available in PDF, EPUB and Kindle. Book excerpt: "This book begins by describing the construction of microwave radiometers at frequencies between 4 and 22 GHz using low cost components acquired from the Internet. The design is based on the lock-in amplifier approach developed by Dr. Robert Dicke in the 1940's. An historic picture of Dicke taking sky measurements using one of his radiometers is shown in the top-left (Figure 41 on page 64). Although microwave technology has advanced considerably, Dicke's basic design hasn't changed much. The radiometers described in this book were used to observe some well known atmospheric and surface features using far field measurements. Also discussed are less understood and more challenging issues pertaining to radiometer calibration and surface emissivity determination using near field measurements. The book ends with three chapters on satellite microwave radiometers. These chapters describe the history and measurements which played a large part in establishing the role of microwave radiometry in earth remote sensing. Examples also reveal unresolved observations that need to be better analyzed and understood after years of launching new satellite instruments. In addition to describing the radiometers and measurements, analytical models are developed to help bridge the gap between observations and their physical interpretation. As such, this book should be of interest to those studying microwave radiometry and its use in remote sensing of the earth's atmosphere and surface. Dr. Norman Grody began his study of microwave radiometry when working at NASA in 1971 at the time when they first began launching experimental instruments on satellites to view earth from space. He then joined NOAA in 1972 working on more advanced radiometers developed by the Air Force, Navy, NASA and NOAA. Until his retirement from NOAA in 2005 he was responsible for evaluating the performance of satellite microwave radiometers and developing algorithms to derive surface and atmospheric parameters from the measurements. These parameters such as temperature, water vapor, rain rate, snow cover, sea ice and sea surface winds are used by various organizations to monitor, analyze and forecast the global weather and climate. The top-right picture (Figure 68 on page 98) shows an example of global.

This book was released on 2018-07-17 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: A conceptual design for the Two-Dimensional, Electronically Steered Thinned Array Radiometer (ESTAR) is described. This instrument is a synthetic aperture microwave radiometer that operates in the L-band frequency range for the measurement of soil moisture and ocean salinity. Two auxiliary instruments, an 8-12 micron, scanning infrared radiometer and a 0.4-1.0 micron, charge coupled device (CCD) video camera, are included to provided data for sea surface temperature measurements and spatial registration of targets respectively. The science requirements were defined by Goddard Space Flight Center. Instrument and the spacecraft configurations are described for missions using the Pegasus and Taurus launch vehicles. The analyses and design trades described include: estimations of size, mass and power, instrument viewing coverage, mechanical design trades, structural and thermal analyses, data and communications performance assessments, and cost estimation.
