This book was released on 2021-05-11 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive review of global ionospheric research from the polar caps to equatorial regions It's more than a century since scientists first identified the ionosphere, the layer of the Earth’s upper atmosphere that is ionized by solar and cosmic radiation. Our understanding of this dynamic part of the near-Earth space environment has greatly advanced in recent years thanks to new observational technologies, improved numerical models, and powerful computing capabilities. Ionosphere Dynamics and Applications provides a comprehensive overview of historic developments, recent advances, and future directions in ionospheric research. Volume highlights include: Behavior of the ionosphere in different regions from the poles to the equator Distinct characteristics of the high-, mid-, and low-latitude ionosphere Observational results from ground- and space-based instruments Ionospheric impacts on radio signals and satellite operations How earthquakes and tsunamis on Earth cause disturbances in the ionosphere The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Download or read book Radio Occultations Using Earth Satellites written by William G. Melbourne and published by Wiley-Interscience. This book was released on 2005 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: the wave theory foundations of today's radio occultation techniques 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. 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. This groundbreaking text provides: An introduction to the general theory of radio occultations Development of ray theory and scalar diffraction treatments of radio propagation processes Development of a wave theoretic treatment of the above wave propagation processes The correspondence between wave and ray theories 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 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. 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.
Download or read book Tropospheric Radiowave Propagation Beyond the Horizon written by François Du Castel and published by Elsevier. This book was released on 2017-04-27 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropospheric Radiowave Propagation Beyond the Horizon deals with developments concerning the tropospheric propagation of ultra-short radio waves beyond the horizon, with emphasis on the relationship between the theoretical and the experimental. Topics covered include the general conditions of propagation in the troposphere; general characteristics of propagation beyond the horizon; and attenuation in propagation. This volume is comprised of six chapters and begins with a brief historical look at the various stages that have brought the technique of transhorizon links to its state of development. The discussion then turns to the physical properties of the troposphere and the phenomenon of tropospheric propagation; influence of the troposphere and the Earth on transhorizon propagation; and theoretical and experimental determination of attenuation in propagation. Experimental data relating to transhorizon propagation are presented. Theories of diffraction and turbulent scattering are described. This book will be helpful to physicists and physics students as well as those who are engaged in the problem of long-range telecommunication and in the interdependence of theory and experience.
Download or read book Ionospheric Techniques and Phenomena written by A. Giraud and published by Springer Science & Business Media. This book was released on 1978-12-31 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: If our eyes were radio rather than optical wide-band detectors it is well known that for us the brightest object in the sky would still be the Sun; that planets, stars and the Milky Way would still shine feebly (and that we would still occasionally be blinded by man-made sources). What is less well known is that quite a different earthbound overcast would hover about us, with its climatic zones, its seasonal changes, its unpredictable storms and scintillating transparence. To be sure, we can get a sort of glimpse of this peculiar type of weather when we tune our receiver to radio broad casting from some remote spot, or photograph the Earth from space at certain specific wavelengths. Nevertheless no one has ever looked at the ionized shroud of the Earth without the help of sophisticated apparatus, and this is one of the reasons why in this domain the phenomena are not easily abstracted from the use of specific techniques. For generations, the study of the ionosphere has been deeply interwoven with the practice of radio communication and detection. Today however, ionospheric physics is best thought of as a branch of space physics; that part of physics which deals with processes at work in the solar system and methods developed for its exploration.

This book was released on 2016-12-14 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph describes the phenomena associated with the propagation of electromagnetic and acoustic waves through atmospheric turbulence. Geared toward specialists in radiophysics and atmospheric acoustics and optics, the treatment is also suitable for advanced undergraduates and graduate students. The author stresses applications to phase and amplitude fluctuations, scintillation of stars, radio scattering, and other problems. Part I covers topics from the theory of random fields and turbulence theory, including statistical description. Part II, on the scattering of waves in the turbulent atmosphere, is supplemented by an appendix on scattering of acoustic radiation. Part III offers a detailed presentation of line-of-sight propagation of acoustic and electromagnetic waves through a turbulent medium. Part IV concludes the text with a comparison of theory with experimental data
