radiowave propagation on satellite-to-ground links at frequencies above 1 GHz and as a reference book for experts in the field. To accomplish this, expanded sections of explanatory text, copiously illustrated, enable an undergraduate or non-specialist to grasp the fundamentals involved. An extensive reference list permits the expert to go to the source material should the level of enquiry go beyond the level of this book. The book is broken down into chapters that deal with the major propagation phenomena classes. After a broad introductory chapter, there are extensively updated chapters on ionospheric effects, clear air effects, attenuation effects and depolarisation effects. New chapters on mobile communications effects and optical communications effects are followed by a chapter on restoration of performance during impairments.
