Book excerpt: In order to provide a state-of-the-art survey of amplitude fluctuations produced by irregularities at F-layer heights in the ionosphere, a survey and review of scintillation phenomena was produced. The survey starts with a definition of scintillation index and a means of characterizing the effect of the amplitude fluctuations on transmissions from a satellite beacon. Various mechanisms proposed for the origin of the irregularity structure are reviewed in light of the observations. The translation of the geophysical information into engineering terms is made so that both depth of fade as a function of latitude and fading rate can be determined; these in turn are used to determine percentage of time scintillations will be a problem at various locations. Characteristics of scintillation dictate modulation systems to be specified for communication and navigation systems employing synchronous satellite beacons at VHF and UHF. Specific problems are addressed. These include low angle or tropospheric scintillations, polar observations, and equatorial irregularities. Variations of scintillation index with magnetic index, angle of elevation, and frequency in these regions as well as middle latitude areas are given. Another atmospheric effect on satellite transmissions is discussed in the final chapter, that is, propagation delays of VHF waves produced by the time delay of radio waves traversing the ionosphere.

This book was released on 2013-03-07 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the years since the pioneering efforts of Sir Edward Appleton, M. A. F. Barnett, G. Breit, and M. A. Thve, many radio techniques have been employed to investigate the terrestrial ionosphere. The purposes of this book are to exam ine the basic physical interaction process of radio waves with the ionosphere, scrutinize each of the radio techniques currently in use, and describe the elements of each technique, as well as assess their capabilities and limitations. I have included some of the history of each technique, since we often tend to forget the efforts of the "pioneers". The interaction of radio waves with the terrestrial ionosphere has been described in considerable detail in several "classic" treatments, e.g., Ratcliffe (1959), Al'pert (1963), Budden (1961) and Davies (1965), Rishbeth and e.g., Flock (1979), Davies Garriott (1969), and in other more recent books, (1990), Hargreaves (1979), and Budden (1985). A few of the radio techniques have been described by Hargreaves (1979) and a book by Giraud and Petit (1978) has also included discussion of several of the techniques. The "WITS" handbook No. 2 (1989) also contains description of several radio techniques.
