Electromagnetic Wave Propagation Through RainClimatic factors such as rain, snow, and other forms of precipitation can have a significant impact on the transmission of radio, light, or heat waves in the atmosphere. Communication systems may experience a loss of signal caused by the effects of rain on a radio link. Radar systems may experience interference that distorts the amplitude of the target signal. Any remote sensing system that relies on the propagation of electromagnetic waves must therefore be designed to take these factors into account.Electromagnetic Wave Propagation Through Rain was written to help system designers in such fields as meteorology, telecommunications, radar, and aircraft guidance systems face the challenge of predicting and compensating for these potentially serious weather-related effects on communication or remote sensing systems around the world and above the surface of the earth.Electromagnetic Wave Propagation Through Rain describes and analyzes the interaction between electromagnetic waves and various forms of precipitation. Interdisciplinary in approach, this book provides a solid in-depth treatment of the underlying physics as well as applications in communications, the aerospace industry, and meteorology.Through a combination of observations and models, Dr. Crane provides both students and practitioners of communication system design with a reliable statistical base for determining the frequency and severity of precipitation- generated attenuation episodes that can significantly impact on vital electromagnetic waves in the atmosphere.An invaluable book for professionals and advanced students in electrical, aerospace, and communications engineering, remote sensing, physics, and meteorology, Electromagnetic Wave Propagation Through Rain represents a significant addition to the literature and an important contribution to our understanding and management of this problem.Precipitation patterns can have a major impact on telecommunication and radar systems around the world. The frequency and duration of rain or snow in any given area at any given time can determine the extent to which vital electromagnetic waves may be compromised—causing interference or even failure in a system. The result of more than 30 years of research, Electromagnetic Wave Propagation Through Rain provides a clear analysis of attenuation by rain and other forms of precipitation on a wide range of vital communication systems.Using observations and models, the author offers predictable statistics of rain events which can help to achieve more effective system designs. Its practical interdisciplinary approach makes Electromagnetic Wave Propagation Through Rain an indispensable resource for engineering professionals and advanced students in electrical, aerospace, and communications engineering.Major topics covered include: Effects of RainRain Structure and Rain-Rate StatisticsRain-Rate Climate ModelsModeling Attenuation by RainAttenuation Mitigation via DiversityWorst-Month StatisticsEstimating Risk

Data and models for better systems designAtmospheric gases, building materials, the weather … The propagation of wireless communications signals depends upon a whole range of factors, any or all of which can have a significant impact on the quality of a signal. Data generated by careful measurement of signals propagating under various environmental conditions are therefore fundamental to designing and building efficient, robust, and economical communication systems.This handbook presents models that describe that data and make predictions for conditions that will affect operational systems. The author-chair of the science panel for the ACTS propagation experiment-focuses on EM waves of 0.3 to 300 GHz propagating through the lower atmosphere. The handbook describes the physical phenomena that can affect propagation, presents sample measurements and statistics, and provides models that system designers can use to calculate their link budgets and estimate the limitations the atmosphere could place on their designs.Communications engineers around the world need this information readily at hand, not scattered throughout the literature. For engineers and systems designers involved in communications, navigation, radar, or remote sensing, the Propagation Handbook for Wireless Communication System Design will quickly become a standard and heavily relied-upon reference.
