  • Ionospheric Radio Propagation

    The effects of the ionosphere on radio propagation are very important in radio communication between the terrestrial antennas and air vehicles (stationary or moving) or satellites. This chapter begins by briefly presenting information about the ionosphere as a continuous medium consisting of plasma, and describes the common effects of ionospheric plasma on radio propagation, following the description of ionospheric effects as well as on the authors' computations. Then, it discusses the effects of large‐scale and small‐scale ionospheric plasma inhomogeneities, and illustrates the main results of signal amplitude and phase variations, that is, the fast fading, resulting from the inhomogeneous structure of the ionosphere, on the basis of numerical computations carried out by the authors according to proposed ionospheric models. Finally, the chapter considers the effects of an inhomogeneous ionosphere on radio propagation at long distances.

  • IONOSPHERIC PROPAGATION

    The amplitude variations of a signal propagating through the ionosphere result from the destructive and constructive interaction of the signal phase resulting from the numerous signal paths through the nonhomogeneous medium; this phenomenon is referred to as scintillation. Signal propagation through the ionosphere is characterized by the refractive index. The refractive index and its influence on the various aspects of a received signal is the subject of this chapter. The chapter characterizes the electron densities in the ionosphere for the natural and nuclear‐disturbed environments and discusses the influence of the electron densities on signal propagation in terms of the refractive index. Application of the index of refraction to a communication link yields the influence of the ionospheric propagation on the received signal. The chapter concludes with a case study of a scintillation scenario using a differentially coherent modulation with interleaving and combining.

  • Fundamental Considerations for GNSS Antennas

    This chapter contains sections titled: GNSS Radio Wave Propagation Antenna Design Fundamentals CP Antenna Design References

  • Transmission Impairments

    The relative importance of radiowave propagation in space communications depends on the frequency of operation, local climatology, local geography, type of transmission, and elevation angle to the satellite. This chapter discusses radiowave propagation in space communications, and introduces the general terms used to describe the propagation phenomena, or propagation mechanisms, which can affect the characteristics of a radiowave. It introduces the major propagation impairments which can affect space communications at frequencies above the ionospheric penetration frequency and up to about 3 GHz. The chapter describes the major propagation impairments, include ionospheric scintillation, polarization rotation, group delay and dispersion, that can hinder space communications in the frequency bands above about 3 GHz. The chapter focuses on line‐of‐site link impairments, additional effects, such as shadowing, blockage and multipath scintillation. The chapter also describes the major radio noise sources in satellite communications, and provides concise methods for the calculation radio noise for the evaluation of communications system performance.
