Aspects of Electromagnetic Wave Scattering in Radio Communications.
Abstract
The scattering of electromagnetic waves is of importance in many communication systems and has been intensively studied in the last quarter of a century. Scattering phenomena can be used to advantage to communicate over the horizon, or they may act adversely as in the case of transmission to a terminal in a jungle or heavily urbanised environment. Examples of the former are the VHF (ionoscatter and meteor-burst) and UHF (troposcatter) links which make use of the scatter from inhomogeneities and discontinuities in the ionosphere and troposphere respectively. Examples of adverse effects occur in relatively short range UHF communications to mobile units surrounded by trees or buildings. A broad review of the state of the art in scatter communication is considered to be both appropriate and timely. The symposium will therefore be concerned with the theory of scattering and reflection in the troposhere, the ionosphere, from meteor trails, and also scattering from ground environmental hazards such as hills, trees and buildings. Included in the propagation aspect will be the prediction of long and short term signal characteristics and modelling of radio channels using scatter mode of propagation. Consideration will also be given to transmission and signal processing techniques for effective communications over such channels. The symposium is thus designed for geophysicists, communication system planners and designers, and also for the users of such systems.
