Over the years since the launch of the first of the Advanced Very High Resolution Radiometers (AVHRRs) in 1978, the data from these instruments have come to be used for a very wide range of non-meteorological applications. In this book, the author describes the satellite system, the instrument itself, the control of the spacecraft and the data- recovery arrangements. The book also covers various aspects of the processing of the data to extract useful environmental information. The applications of the data to marine problems, based primarily on the study of sea-surface temperatures from the thermal-infrared channels of the instrument, are considered, as well as the study of vegetation and a whole variety of other land-based and hydrological applications.
The Visible Infrared Imager Radiometer Suite (VIIRS) is the next-generation multispectral imaging instrument to fly on US operational, polar-orbiting meteorological satellites. VIIRS will gather data across 22 spectral bands and be used to create products for a variety of applications including weather forecasting and climate change studies. VIIRS consolidates the best features of heritage instruments, including near-constant resolution and nighttime visible imagery. Visible Infrared Imager Radiometer Suite: A New Operational Cloud Imager provides the first comprehensive guide on the design and exploitation of cloud data collected by the VIIRS.
the wave theory foundations of today's radio occultation techniques<br> <br> Forty years ago, the premier radio occultation problem was how to profile the atmosphere and radius of Mars using signals sent by the Mariner 4 spacecraft. Researchers then could rely on ray theory-based techniques for accurate analysis of the thin, uniform Martian atmosphere. Today's radio occultation challenges mostly involve communications platforms-and related data, instrument systems, and applications-in the Earth's own atmosphere. To deal with the density and complexity of this multilayered medium, an analytical framework that goes beyond ray theory is needed.<br> <br> Setting the cutting edge for the field, Radio Occultations Using Earth Satellites: A Wave Theory Treatment develops a purely wave-theoretic approach to occultation analysis. This approach yields more nuanced results than either ray or hybrid (ray/wave) methodologies offer, and proves suitable for the many variables at work in today's problems.<br> <br> This groundbreaking text provides:<br> * An introduction to the general theory of radio occultations<br> * Development of ray theory and scalar diffraction treatments of radio propagation processes<br> * Development of a wave theoretic treatment of the above wave propagation processes<br> * The correspondence between wave and ray theories<br> * A discussion of how to use a wave-theoretic approach to infer the refractive properties of the propagation medium from a time series set of observations of the propagated wave's phase and amplitude<br> <br> A comprehensive resource that clearly defines the latest topics and methodologies, Radio Occultations Using Earth Satellites is a must-have text for engineers, scientists, students, and managers in satellites communications, navigation, deep space and planetary exploration, aerospace, atmospheric science, physics, and engineering.<br> <br> The Deep Space Communications and Navigation Series is authored by scientists and engineers with extensive experience in astronautics, communications, and related fields. It lays the foundation for innovation in the areas of deep space navigation and communications by disseminating state-of-the-art knowledge in key technologies.
In clear, easy-to-grasp language, the author covers many of the topics that you will need to know in order to launch and run a successful business venture.
<b>Comprehensive, authoritative coverage of interferometric techniques for radio astronomy</b> <p> In this Second Edition of <i>Interferometry and Synthesis in Radio Astronomy</i>, three leading figures in the development of large imaging arrays, including very-long-baseline interferometry (VLBI), describe and explain the technology that provides images of the universe with an angular resolution as fine as 1/20,000 of an arcsecond. <p> This comprehensive volume begins with a historical review followed by detailed coverage of the theory of interferometry and synthesis imaging, analysis of interferometer response, geometrical relationships, polarimetry, antennas, and arrays. Discussion of the receiving system continues with analysis of the response to signals and noise, analog design requirements, and digital signal processing. <p> The authors detail special requirements of VLBI including atomic frequency standards, broadband recording systems, and antennas in orbit. Further major topics include: <ul> <li>Calibration of data and synthesis of images <li>Image enhancement using nonlinear algorithms <li>Techniques for astrometry and geodesy <li>Propagation in the neutral atmosphere and ionized media <li>Radio interference <li>Related techniques: intensity interferometry, moon occultations, antenna holography, and optical interferometry </ul> <p> <i>Interferometry and Synthesis in Radio Astronomy, Second Edition</i> is comprehensive in that it provides an excellent overview of most radio astronomical instrumentation and techniques.
